HEAVY-LIGHT MESONS IN THE SYMMETRIES OF EXTENDED NONRELATIVISTIC QUARK MODEL
Yanbu Journal of Engineering and Science, 2019 In present work, the modified Schrödinger equation (MSE) is analytically solved. The Heavy-Light Mesons (HLM) under modified nonrelativistic quark-antiquark potential, are extended to the symmetries of noncommutative quantum mechanics (NCQM), using the ...

Z2×Z2-graded mechanics: The quantization
Nuclear Physics B, 2021 In a previous paper we introduced the notion of Z2×Z2-graded classical mechanics and presented a general framework to construct, in the Lagrangian setting, the worldline sigma models invariant under a Z2×Z2-graded superalgebra. In this work we discuss at

Quantum mechanics and hidden superconformal symmetry [PDF]
Physical Review D, 2017 Solvability of the ubiquitous quantum harmonic oscillator relies on a spectrum generating osp(1|2) superconformal symmetry. We study the problem of constructing all quantum mechanical models with a hidden osp(1|2) symmetry on a given space of states. This problem stems from interacting higher spin models coupled to gravity.

Tools for Verifying Classical and Quantum Superintegrability [PDF]
, 2010 Recently many new classes of integrable systems in n dimensions occurring in classical and quantum mechanics have been shown to admit a functionally independent set of 2n−1 symmetries polynomial in the canonical momenta, so that they are in fact ...

An Argument for 4D Blockworld from a Geometric Interpretation of Non-relativistic Quantum Mechanics [PDF]
, 2007 We use a new, distinctly “geometrical” interpretation of non-relativistic quantum mechanics (NRQM) to argue for the fundamentality of the 4D blockworld ontology.

Particle Indistinguishability Symmetry within a Field Theory. Entropic Effects
Entropy, 2009 In this paper, we briefly discuss a field theory approach of classical statistical mechanics. We show how an essentially entropic functional accounts for fundamental symmetries related to quantum mechanical properties which hold out in the classical ...

Generalized Heisenberg-Weyl groups and Hermite functions
SciPost Physics Proceedings, 2023 A generalisation of Euclidean and pseudo-Euclidean groups is presented, where the Weyl-Heisenberg groups, well known in quantum mechanics, are involved. A new family of groups is obtained including all the above-mentioned groups as subgroups. Symmetries,

Realism and time symmetry in quantum mechanics [PDF]
Physics Letters A, 1995 We describe a gedanken experiment with an interferometer in the case of pre- and postselection in two different time symmetric ways: We apply the ABL formalism and the de Broglie--Bohm model. Interpreting these descriptions ontologically, we get two very different concepts of reality. Finally, we discuss some problems implied by these concepts.

Spontaneous symmetry breaking in quantum mechanics [PDF]
American Journal of Physics, 2007 We present a mathematically simple procedure to explain spontaneous symmetry breaking in quantum systems. The procedure is applicable to a wide range of models and can be easily used to explain the existence of a symmetry broken state in crystals, antiferromagnets, and even superconductors.
