In a Hamiltonian approach to anomalies, parity and time-reversal symmetries can be restored by introducing suitable impure (or mixed) states. However, the expectation values of observables such as the Hamiltonian diverges in such impure states. Here, we show that such divergent expectation values can be treated within a renormalization group (RG) framework, leading to a set of β-functions in the moduli space of the operators representing the observables. This leads to well-defined expectation values of the Hamiltonian in a phase where the impure state restores the P and T symmetry. We also sho

Aims. We aim to present a first step in developing a benchmark equation-of-state (EoS) model for multi-messenger astronomy that unifies the thermodynamics of quark and hadronic degrees of freedom. Methods. A Lagrangian approach to the thermodynamic potential of quark-meson-nucleon matter was used. In this approach, dynamical chiral-symmetry breaking is described by the scalar mean-field dynamics coupled to quarks and nucleons and their chiral partners, whereby its restoration occurs in the hadronic phase by parity doubling, as well as in the quark phase. Quark confinement was achieved by an au

We study dynamical chiral symmetry breaking (DCSB) in an effective QED3 theory of d-wave high temperature cuprate superconductors under a uniform magnetic field. At zero temperature, the external magnetic field induces a mixed state by generating vortices in the condensate of charged holons. The growing magnetic field suppresses the superfluid density and thus reduces the gauge field mass which is opened via the Anderson–Higgs mechanism. By numerically solving the Dyson–Schwinger gap equation, we show that the massless fermions acquires a dynamical gap through DCSB mechanism when the magnetic

We present the angular and kinetic energy distributions for the products of the proton transfer reaction O− + HF → OH + F− at center-of-mass collision energies of 45.0 and 55.8 kJ mol−l (0.47 and 0.58 eV, respectively). At both collision energies, the product angular distributions show forward–backward symmetry, characteristic of the decay of a transient complex living at least several rotational periods. The product kinetic energy distributions show structure that is clearly attributable to the formation of OH in v′ = 0,1, and 2. The kinetic energy distribution for a single vibrational state

Studying meson structures is essential for gaining insights into the nonperturbative nature of Quantum Chromodynamics (QCD). This study will focus on calculating the decay constant and distribution amplitudes (DAs) of unflavored light mesons (π and ρ) in the 1S and 2S states using the Light Front Quark Model. This study utilizes the QCD-motivated Hamiltonian, taking into account both contact and smeared spin-spin interactions. The two lowest harmonic oscillator bases are employed in this work to achieve improved results for the 2S states. The study found the optimal mixing parameter in basis e

For the last several decades, there has been tremendous interest in search for Supersymmetry (SUSY) in the area of high energy physics. At Large Hadron Collider (LHC), there have been continuous searches for SUSY for prompt and non-prompt, for particle R-parity conserving and R-parity violating generation and decays. The limits obtained from these experiments and analyses for detection of the signatures of supersymmetric particles (LSP), revealed greater possibilities of such experiments in the collider. However, these signatures are usually derived under the assumption of bit optimistic condi

Collective nuclei are characterized by rotational and vibrational states due to a common and therefore ``collective'' behavior of the two constituents of the nucleus: protons and neutrons. The evolution of the collectivity (spontaneous deformation) is governed by the proton-neutron interaction in the valence shell. Nuclear states that are particularly sensitive to the proton-neutron interaction in the valence shell are the so called mixed symmetry states (MSSs). In this work we trace the evolution of the fundamental MSS, i.e the one-quadrupole phonon 2+_1,ms state, in a transitional region fro

Abstract Three aspects of the solid state chemistry of tin are discussed.

Electronic conductivity and IR reflectivity are enhanced without loss of transparency in the visible; applications to solar energy conversion are considered. The use of Sn Mossbauer spectroscopy is described in the second section to show that the technique is able to give quantitative information about bond covalency as well as the symmetry of the Sn(II) and Sn(IV) environments; mixed fluorides h

Superconductivity is a major research field in which the use of muons has made an important contribution. Muons measure the London penetration depth, the distance over which the superconductor screens an external magnetic field. In type-II superconductors that support the Abrikosov flux lattice in the mixed state, the square root of the second moment of the precession frequency distribution at the muon site produced by the flux lattice is proportional to the London penetration depth. Zero-field measurements allow spontaneous fields due to time-reversal symmetry breaking to be observed in the s

Abstract The dynamic behavior of spiral-grooved gas bearing supported 4DoF rotors is investigated by means of linearized bearing force coefficients and full time-integrated transient analysis. The transient method consists of a state-space representation, which couples the equations of motion with the compressible thin film fluid equation. The linearized method is based on the perturbation analysis around a given eccentric shaft position ε, allowing to compute the static and linear dynamic bearing force coefficients at different excitation frequencies.

In birefringent optical fibers, linearly-polarized solitons associated with the fast mode become unstable at a certain power level [1,2]. A similar instability exists in planar waveguides made from isotropic materials [3]. It has been shown for the first time in [4,5], that the physical reason for this instability in isotropic materials is the appearance of new elliptically-polarized solitons above a certain critical power. In this work we prove that new solitons also exist in media with cubic anisotropy. Moreover, we have found that in planar waveguides made from cubic crystals, the symmetry

This leads to nonlinear modal interactions of a pair of 1 – 1 internally resonant, asymmetric modes which are studied through first-order averaging.

Abstract Thermoacoustic oscillations in axisymmetric annular combustors are generally coupled by degenerate azimuthal modes, which can be of standing or spinning nature. Symmetry breaking due to the presence of a mean azimuthal flow splits the degenerate thermoacoustic eigenvalues, resulting in pairs of counter-spinning modes with close but distinct frequencies and growth rates. In the present study, experiments have been performed using an annular system where the thermoacoustic feedback due to the flames is mimicked by twelve identical electroacoustic feedback loops.
