Abstract:
Quantum mechanics presently has many unanswered questions, paradoxes, and even outright logical contradictions. To make progress in understanding quantum mechanics, we begin by proposing that relativity be set aside in favor of an absolute aetherial theory. Once that step is taken, we can understand quantum collapse as a description of real wave-packets collapsing in a faster-than-light way. By assuming that a partially observable reality exists, we can then extend our analysis of wave-packets into the subquantum, and the Heisenberg uncertainty principle then follows from the Fourier uncertain

Abstract:
Nos últimos anos, a palavra “quântico” tem sido utilizada em contextos variados, muitas vezes dissociados de sua origem na física quântica. Termos como “coach quântico” e “cura quântica” são exemplos de como conceitos científicos podem ser desvirtuados para finalidades metafísicas ou pseudocientíficas. Este artigo explora a origem do termo “quântico”, suas bases teóricas na física e seu uso na ficção científica, onde se tornou um recurso narrativo popular. A mecânica quântica, que estuda os fenômenos no nível subatômico, foi desenvolvida por cientistas como Einstein, Bohr, Planck, Schrödinger

Abstract:
We present an introductory study of the role of the particle concept in the foundational papers of quantum mechanics. We focus on the period, 1925-1927, which includes the analysis of the first papers by Heisenberg, Born, Jordan, Schrödinger and Dirac, and also the first formulation of Bohr's complementarity. Our aim is to discuss to what extent the concept of particle was questioned among the creators of the new theory, just at the time of its creation and when there was still no agreed or established interpretation. Subsequent developments, such as quantum field theory, put the validity of t

Abstract:
The generation of squeezed states of light in a two-mode Kerr nonlinear directional coupler (NLDC) was investigated using two different methods in quantum mechanics. First, the analytical method, a Heisenberg-picture-based method where the operators are evolving in time but the state vectors are time-independent. In this method, an analytical solution to the coupled Heisenberg equations of motion for the propagating modes was proposed based on the Baker–Hausdorff (BH) formula. Second, the phase space method, a Schrödinger-picture-based method in which the operators are constant and the density

Abstract:
The foundations of quantum physics have been laid by Max Planck, who suggested that energy couldn’t be absorbed and radiated continuously, but only in separate portions - these portions were called quanta. His ideas were confirmed in numerous physical experiments on the photo effect, the structure of the atom and atomic nucleus, brilliantly performed by Bohr and Rutherford. All this in the aggregate made it possible to eliminate the border between matter and waves, predicted by Louis de Broil. In this way the foundations of quantum mechanics were laid = Heisenberg and Schrödinger did this work

Noncommutativity in physics has a long history, tracing back to classical mechanics. In recent years, many new developments in theoretical physics, and in practical applications rely on different techniques of noncommutative algebras. In this review, we introduce the basic concepts and techniques of noncommutative physics in a range of areas, including classical physics, condensed matter systems, statistical mechanics, and quantum mechanics, and we present some important examples of noncommutative algebras, including the classical Poisson brackets, the Heisenberg algebra, Lie and Clifford alge

In the book The Structure of Relativistic and Quantum Revolutions in Physics, I presented the anti-Kuhnian and anti-Lakatosian model of scientific revolutions. Following Fleck, I assume that scientists’ ways of perceiving phenomena and thinking about them are conditioned by the thought style acquired in the process of being introduced to the profession. So how could it happen that scientists at the turn of the 19th and 20th centuries began to think differently than they had been taught to think? My answer is that both revolutions were made by three generations of theorists. In the first genera

From classical mechanics, in particular the motion in a straight line, together set theory and ordinal number theory, we prove a not-classical behaviour, a discontinuous motion and emission. Now we have obtained that the not-classical behaviour is essentially due to ∄n(ω = S(n)). But incredibly this could have been discovered about 140 years ago, before Planck theory. So quantum behaviour looks very natural and classical mechanics has to be rejected. The classical limit h = 0 cannot exist. The most important theories describe Quantum behavior.

The damping of the harmonic oscillator is studied in the framework of the Lindblad theory for open quantum systems. A generalization of the fundamental constraints on quantum mechanical diffusion coefficients which appear in the master equation for the damped quantum oscillator is presented; the Schrödinger, Heisenberg and Weyl-Wigner-Moyal representations of the Lindblad equation are given explicitly. On the basis of these representations it is shown that various master equations for the damped quantum oscillator used in the literature are particular cases of the Lindblad equation and that no

In the first case study, DFB was applied to obtain the Boltzmann PDE, whose solution is a distribution for Boltzmann gas. Following, the Planck photon gas in the Radiation Law, Fermi–Dirac, and Bose–Einstein distributions were also verified as solutions to the Boltzmann PDE. The first case study demonstrates the importance of the Boltzmann PDE and the DFB method, both introduced in this paper. In the secon
