Twist Fields in Many-Body Physics [PDF]

Entropy
The notion of twist fields has played a fundamental role in many-body physics. It is used to construct the so-called disorder parameter for the study of phase transitions in the classical Ising model of statistical mechanics, it is involved in the Jordan–

Temporal Anti-Parity–Time Symmetry: Extending Non-Hermitian Physics to Time-Domain Dynamics in Thermal Diffusion [PDF]

Research
Parity–time and anti-parity–time symmetries, originally formulated in the context of non-Hermitian quantum mechanics, have now been experimentally realized across diverse physical platforms, including photonic, wave-guiding, acoustic, and mechanical ...

Entropic Dynamics Approach to Quantum Electrodynamics [PDF]

Entropy
Entropic Dynamics (ED) is a framework that allows one to derive quantum theory as a Hamilton–Killing flow on the cotangent bundle of a statistical manifold.

“The Creative Force of Mathematical Formulations”: Werner Heisenberg and the Past, Present, and Future of Quantum Theory [PDF]

Entropy
This article offers a new argument concerning the relationships between mathematics and physical reality in quantum theory. While, as dedicated to the centenary of Heisenberg’s invention of quantum mechanics, the article contains a historical discussion,

Lie symmetries and superintegrability in quantum mechanics

Physics of Atomic Nuclei, 2002
Starting from the structure of the higher order Lie symmetries of the Schrodinger equation in the Euclidean plane E2, we establish, in the case of first-and second-order symmetries, the relations between separation of variables and superintegrable systems in quantum mechanics.

Symmetries in Quantum Mechanics [PDF]

, 1989
Symmetries play a fundamental role in physics, and knowledge of their presence in certain problems often simplifies the solution considerably. We illustrate this with the help of three important examples.

The group structure of dynamical transformations between quantum reference frames [PDF]

Quantum, 2021
Recently, it was shown that when reference frames are associated to quantum systems, the transformation laws between such quantum reference frames need to be modified to take into account the quantum and dynamical features of the reference frames.

Symmetry fundamentalism in quantum mechanics [PDF]

Philosophical Studies, 2021
AbstractModern particle physics suggests an intriguing vision of physical reality: we are to imagine the symmetries of the world as fundamental, whereas the material constituents of the world (such as particles and fields) are ontologically derivative of them.

Dirac Equation for Energy-Dependent Potential With Energy-dependent Tensor Interaction

Journal of Nigerian Society of Physical Sciences, 2023
The relativistic symmetries of the Dirac equation were investigated with an energy-dependent tensor potential interaction for two different energy-dependent potentials under parametric Nikiforov-Uvarov method and supersymmetric quantum mechanics and ...
