Abstract:
The author examines the peculiarities of the reception of L.N. Andreev, reflected in the literary-critical articles of D.V. Filosofov, written in 1907. The features of his critical method are characterized. It is shown that the interpretation of Andreev’s works in these works of Filosofov was subordinated to the concept of building a “new religious consciousness”, developed by him together with his spiritual allies — D.S. Merezhkovsky and Z.N. Gippius. In 1907, the creative personality of Andreev was still characterized by Filosofov as a “background” figure, in comparison with the personality of Gorky and the cohort of realists united around the publishing house called “Knowledge”. The critic saw the damage to Andreev’s world outlook in the writer’s rejection of “culture”, “consciousness” and “religious community”. At the same time, he strenuously tried to “cut off” Andreev from the “philosophy” of Gorky and the realists of the Gorky circle. In addition, Andreev’s ideological and artistic quest was investigated by Filosofov in the context of such a complex literary phenomenon at the turn of the century as “mystical anarchism”. In general, the critical assessments of Andreev’s work presented in the articles of Filosofov in 1907 are ambiguous and dialectical. Revealing the “strength” and “weakness” of Andreev the artist, Filosofov in many ways showed himself as a critic and “educator”. He not only waged a struggle with Andreev, the singer of pessimism, despair and “nothingness”, but also tried to direct this talented writer along the “correct” ideological path, turn the vector of his creative movement towards “religious revival”, that is, “new Christianity”.

Abstract:
The published diary entries of the famous literary critic and bibliographer V.N. Chuvakov are devoted to his meetings with the actress E.A. Polevitskaya in 1958–1961. In the text there is an image of an actress who was extremely popular in the 1910s, who had a long and difficult creative path, but still needed theater and acting. From Polevitskaya’s memoirs about her theatrical activity and about the theater of the early 20th century Chuvakov builds the main plot for him, associated with the name of Leonid Andreev. Fragmentary, inconsistent, but vivid, the actress’ memories about her creative relationships and personal meetings with Andreev complement our ideas about the writer, bring new shades to the picture of theatrical and artistic life of the early 20th century. The publication includes a letter from Polevitskaya to prof. K.I. Platonov, the author of a “forensic psychopathological study” on Andreev’s play “Ekaterina Ivanovna.” In the letter, the actress expounds her original, deep interpretation of the image of the mysterious and attractive Ekaterina Ivanovna and the motivation for her actions. Chuvakov's notes create an idea of Polevitskaya as an actress, capable of seriously, analytically approaching work on the role, delving deeply into the author's intention, which makes the diary's author's conclusion reasonable: Polevitskaya is the best Ekaterina Ivanovna (the heroine of Andreev's play).

Abstract:
The article is a review of the childhood memories' book by Leonid Andreev's granddaughter O. Andreeva-Carlisle — the novella “An Island for Life,” first translated (by L. Shenderova-Fock) into Russian from English and French, the languages of the first publications. In the novel, the author recreates the five-year period (1939–1945) of her family's stay on the island of Oleron, occupied by the Nazis, reconstructs the “Russian world” of the diaspora, created by reading books, socializing with compatriots (G. Fedotov, M. Tsvetaeva, A. Remizov, etc.), and ardent interest in Russia. The review analyzes the genre of the book, which combines fidelity to fact with fictionalization of documentary material in the spirit of a girly story; it also reveals the “book code,” allowing the author to romanticize the narrative and present the events of the Resistance, in which the family was included, in an adventurous manner. It is demonstrated that the depicted events and the atmosphere in the village of Saint-Denis on the ocean coast are associated in the book with the artistic world of E.A. Poe, read aloud to the children by their father, Vadim, who lived as a child in Finland in a house on the Black River. The image of the author’s famous grandfather, the Russian writer Leonid Andreev, recreated from the stories, also merges with the notion of the American romantic Poe. The portrait of Leonid Andreev in the book appears mythologized, refracted by the prism of perception of his son Vadim and determined by the literary reputation of the writer himself.

Abstract:
Many of the properties of superconductors related to quantum coherence are revealed when the superconducting state is forced to vary in space in response to an external magnetic field, a proximity contact, an interface to a ferromagnet or to impurities embedded in the superconductor. Among the earliest examples is Andreev reflection of an electron into a retro-reflected hole at a normal-superconducting interface. In regions of strong inhomogeneity, multiple Andreev reflection leads to the formation of sub-gap states, Andreev bound states , with excitation energies below the superconducting gap. These states play a central role in our understanding of inhomogeneous superconductors. The discoveries of unconventional superconductivity in many classes of materials, advances in fabrication of superconducting/ferromagnetic hybrids and nanostructures for confining superfluid 3 He, combined with theoretical developments in topological quantum matter have dramatically expanded the significance of branch conversion scattering and Andreev bound state formation. This collection of articles highlights developments in inhomogeneous superconductivity, unconventional superconductivity and topological phases of superfluid 3 He, in which Andreev scattering and bound states underpin much of the physics of these systems. This article provides an introduction to the basic physics of Andreev scattering, bound-state formation and their signatures. The goal is both an introduction for interested readers who are not already experts in the field, and to highlight examples in which branch conversion scattering and Andreev bound states provide unique signatures in the transport properties of superconductors. This article is part of the theme issue ‘Andreev bound states’.

Abstract:
Andreev bound states are ubiquitous in superconducting hybrid structures. They are formed near impurities, in Josephson junctions, in vortex cores and at interfaces. At spin-active superconductor–ferromagnet interfaces, Andreev bound states are formed due to spin-dependent scattering phases. Spin-dependent phase shifts are an important ingredient for the generation of triplet Cooper pairs in superconductor–ferromagnet hybrid structures. Spectroscopy of Andreev bound states is a powerful probe of superconducting order parameter symmetry, as well as spin-dependent interface scattering and the triplet proximity effect.

Abstract:
Andreev bound states are an expression of quantum coherence between particles and holes in hybrid structures composed of superconducting and non-superconducting metallic parts. Their spectrum carries important information on the nature of the pairing, and determines the current in Josephson devices. Here, I focus on Andreev bound states in systems involving superconductors and ferromagnets with strong spin-polarization. I provide a general framework for non-local Andreev phenomena in such structures in terms of coherence functions, and show how the latter link wave function and Green-function based theories.

Abstract:
Abstract We have investigated crossed Andreev reflection in a ferromagnet-superconductor-ferromagnet junction based on the time-reversal invariant Weyl semimetals. We demonstrate that this junction can provide a suitable platform for generating pure crossed Andreev reflection signals. For bipolar junction, n-doped left ferromagnet and p-doped right ferromagnet, pure co-tunneling can happen in the antiparallel configuration of the magnetizations of ferromagnets, while a pure crossed Andreev reflection is possible only in the parallel configuration. However, when both of the ferromagnetic leads have the same polarity, n-doped or p-doped, the situation is reversed. Furthermore, we find that we can tune the chemical potentials and magnetizations of the ferromagnets separately to on or off co-tunneling and crossed Andreev reflection signals. Moreover, we show that the pure crossed Andreev reflection signal can be enhanced by tuning the chemical potentials of two ferromagnetic leads. Our findings may be employed for generating entangled electron pairs in the condensed matter systems.

Full text
Abstract:
The paper aims to describe the impact of judicial thinking on the style and imagery of L. Andreev’s prose. The research provides a theoretical interpretation of such central symbol-metaphors related to judicial issues as court, sentence, defence, and prosecution. The study draws parallels between the writer’s biography and the existential themes which L. Andreev reproduces in his writings by applying specialised terminology to metaphysical problems. To identify the above-mentioned parallels, traditional literary analysis is employed. It aims to generalise the writer’s aesthetic views on literature in the light of the judicial peculiarities of his thinking. Particular attention is directed to the influence of judicial stylistics on the poetics of L. Andreev’s writings. As a result, the application of linguostylistic analysis (aimed mainly at examining the lexical and syntactic structure of L. Andreev’s texts) enables the author of the paper to conclude that there is a sudden reorientation of the writer’s artistic strategy. L. Andreev replaced the rhetorical expressionist impact on the reader’s mind with the sharp, abrupt syntax of the story "The Seven Who Were Hanged". The form of judicial rhetoric manifestation also changed. The author substituted the deliberately monotonous stringing of "formulae-sentences" for the ornamental suggestion of the previously used techniques. The concise and compressed bare phrase became the method of conveying the author’s marked tendency that is indicative of the enormity of executions. The methods of statistical calculation and the linguostylistic analysis of excerpts from the short story "The Seven Who Were Hanged" were used to reinforce the derived conclusions. Additionally, theoretical material which helps to comprehend the specific features of courtroom prosecution speeches with regard to L. Andreev’s texts is analysed. The literary generalisations provided in the paper can be used in Russian language and literature lessons.

Abstract:
This is the first complete publication of Leonid Andreev’s letters to his first lover, Zinaida Nikolaevna Sibileva. The course of their relationships between 1889 and 1892 was stormy and very uneven. The letters reveal a lot of previously unknown features of Andreev’s life as a schoolboy and student. But more important is a certain diary of writer’s “mental states” reflected in them, the stream of his complex, sometimes “borderline” psychological experiences. Believing (with a reference to the authority of Maupassant) that the letters most accurately highlight the personality of a person, that they “reveal the soul without any embellishment,” Andreev at the same time regarded his epistolary opuses (as well as his diaries) as a kind of writing exercise.

Abstract:
Effect of proximity-induced unconventional p-wave superconductivity in a three-dimensional topological insulator-based S/F/S structure on the Andreev bound states (ABSs) and Josephson supercurrent is studied. We investigate, in detail, the suppression of Andreev reflection and helical ABSs in the presence of three types of triplet superconducting gap. The magnetization of ferromagnetic section is perpendicular to the surface of junction. The influence of such features on the supercurrent flow on the surface of the topological insulator is studied. We carry out our goal by introducing a relevant form of Dirac spinors for gapless renormalized by chemical potential μ excitation states. Therefore, it enables us to consider the virtual Andreev process, simultaneously, and we propose to investigate it in a tunneling conductance junction. It is shown that the results obtained in this case are completely different from those in conventional superconductivity, as s- or d-waves, for example, the magnetization is found to decrease the gap for px and px+ipy case, whereas increase it for py order. Strongly suppressed Andreev reflection is demonstrated.

Abstract:
We study the quantum interference (QI) effects in three-terminal Andreev interferometers based on polyaromatic hydrocarbons (PAHs) under non-equilibrium conditions. The Andreev interferometer consists of a PAH coupled to two superconducting and one normal conducting terminals. We calculate the current measured in the normal lead as well as the current between the superconducting terminals under non-equilibrium conditions. We show that both the QI arising in the PAH cores and the bias voltage applied to a normal contact have a fundamental effect on the charge distribution associated with the Andreev Bound States (ABSs). QI can lead to a peculiar dependence of the normal current on the superconducting phase difference that was not observed in earlier studies of mesoscopic Andreev interferometers. We explain our results by an induced asymmetry in the spatial distribution of the electron- and hole-like quasiparticles. The non-equilibrium charge occupation induced in the central PAH core can result in a π transition in the current-phase relation of the supercurrent for large enough applied bias voltage on the normal lead. The asymmetry in the spatial distribution of the electron- and hole-like quasiparticles might be used to split Cooper pairs and hence to produce entangled electrons in four terminal setups.

Abstract:
AbstractGrowth rates and the ability to date an organism can greatly contribute to understanding its population biology and community dynamics. 1n 1954, V. N. Andreev proposed a method to date regularly branched members of Cladonia, a fruticose lichen, using total thallus length and number of internodes. No research, however, has demonstrated the reliability of this technique or compared its estimates to those derived by other means. In this study, we demonstrate the utility of 14C/C ratios to determine lichen age and growth rate in Cladonia stygia (Fr.) Ruoss collected from north-western Alaska, USA. The average growth rate using 14C/C ratios was 6·5 mm yr−1, which was not significantly different from growth rates derived by Andreev's internode method (average = 6·2 mm yr−1); thus, suggesting the reliability of Andreev's simple field method for dating lichens.

Abstract:
Abstract We theoretically investigate the Andreev reflection of the massive pseudospin-1 Dirac fermions including the +U-type, the −U-type, and the S z -type mass terms, corresponding to the flat band locating at the top, the bottom, and the center of the band gap, respectively. For the ±U-type fermions, it is found that the Andreev reflection probability at the oblique incidence can be even larger than that at the normal incidence. For the retro-reflection, such an oblique enhancement occurs in the n-doped +U-type (p-doped −U-type) massive fermion systems. While for the specular reflection, the enhancement occurs in the n-doped −U-type (p-doped +U-type) systems. For the S z -type massive fermions, an ideal Andreev reflection with all-angle unit efficiency is predicted in an undoped junction with the incident energy equal to the superconducting gap.

Abstract:
This paper reviews confinement-driven phase transitions in superconductors and Bardeen–Cooper–Schrieffer superfluids, and the appearance in thin films of new phases that break the time-reversal or translational symmetry. The origins of the new phases are closely tied to the Andreev scattering processes involving particle-hole conversions that create surface quasiparticle states with energies inside the superconducting gap. Restructuring of the low-energy spectrum in the surface region of several coherence lengths ξ 0 results in large spatial variations of the superconducting order parameter. In confined geometry, such as slabs, films, pores or nano-dots, with one or more physical dimensions D ∼10 ξ 0 , the Andreev bound states can dominate properties of a superconductor, leading to modified experimental signatures. They can significantly change the energy landscape, and drive transitions into new superconducting phases. The new phases are expected in a variety of materials, from singlet d -wave superconductors to multi-component triplet superfluid 3 He, but properties of the new phases will depend on the symmetry of the parent state. I will highlight the connection between the Andreev surface states and confinement-stabilized phases with additional broken symmetries, describe recent progress and open questions in the theoretical and experimental investigation of superfluids in confined geometry. This article is part of the theme issue ‘Andreev bound states’.

Abstract:
The purpose of this article is to provide an objective study of the process of the return of the Uniates (Greek Catholics) to the Russian Orthodox Church in lands which departed from the Polish Commonwealth to the Russian Empire. Historiography has strengthened the view that the transitions of the Uniates to Orthodoxy have always been voluntary and even desirable. At the same time, historians utilized numerical data on conversions to Orthodoxy, very rarely utilizing primary sources. The analysis of memoirs (the writings of government officials on whom the implementation of the policy of religious appeals depended) undertaken in this article, shows that, in fact, there were protests from the Uniate population against violent Orthodoxy. The systemic approach (the method of structural systematization) is utilized in our work, making it possible to examine interconfessional relationships both from the positions of representatives of the authorities and from the Uniate community.

Abstract:
The review is a detailed analysis of the premiere performance “The Story of the Seven”, based on the “The Story of the Seven Who were Hanged” by Leonid Andreev directed by Ivan Komarov on the “Other” Stage of the Sovremennik Theater at the end of 2021. The author of the review focused on the problem of “translating” the epic work into the language of drama. Particular attention is paid to the “key” moments of the prose text, which became an impulse for the director, pushing him to the figurative embodiment of the word. A comparison of the composition of Andreev’s story with the compositional solution of the play is made. It also is pointed to a particular expressionism of the stage performance, which does not coincide with the stylistic of Andreev’s expressionism, which shows the freshness and originality of the director’s and actors’ approach.

Abstract:
Abstract Boundary conditions for kinetic equations describing the dynamics of electrons in the metal were analyzed. The boundary condition of the Fuchs and the boundary condition of Soffer were considered. The Andreev conditions for almost tangential moving electrons were taken into account. It is shown that the Soffer boundary condition does not satisfy this condition. The boundary condition was proposed that satisfies the Andreev condition. It is shown that this boundary condition passes in the limiting case into the mirror–diffuse Fuchs boundary condition.
