Berry's phase in noncommutative spaces [PDF]

open access: yes, 2002
We introduce the perturbative aspects of noncommutative quantum mechanics. Then we study the Berry's phase in the framework of noncommutative quantum mechanics. The results show deviations from the usual quantum mechanics which depend on the parameter of

Quantum Information Dimension and Geometric Entropy

open access: yesPRX Quantum, 2022
Geometric quantum mechanics, through its differential-geometric underpinning, provides additional tools of analysis and interpretation that bring quantum mechanics closer to classical mechanics: state spaces in both are continuous and equipped with ...

Deep Potential Molecular Dynamics: a scalable model with the accuracy of quantum mechanics [PDF]

open access: yesPhysical Review Letters, 2017
We introduce a scheme for molecular simulations, the deep potential molecular dynamics (DPMD) method, based on a many-body potential and interatomic forces generated by a carefully crafted deep neural network trained with ab initio data.

SUSUSY Quantum Mechanics [PDF]

open access: yesInternational Journal of Modern Physics A, 1997
The exactly solvable eigenproblems in Schrödinger quantum mechanics typically involve the differential "shift operators". In the standard supersymmetric (SUSY) case, the shift operator turns out to be of first order. In this work, I discuss a technique to generate exactly solvable eigenproblems by using second order shift operators.

Probability, Entropy, and Gibbs’ Paradox(es)

open access: yesEntropy, 2018
Two distinct puzzles, which are both known as Gibbs’ paradox, have interested physicists since they were first identified in the 1870s. They each have significance for the foundations of statistical mechanics and have led to lively discussions with

The Many Classical Faces of Quantum Structures

open access: yesEntropy, 2017
Interpretational problems with quantum mechanics can be phrased precisely by only talking about empirically accessible information. This prompts a mathematical reformulation of quantum mechanics in terms of classical mechanics.

Quasi-relativistic description of a quantum particle moving through one-dimensional piecewise constant potentials

open access: yesResults in Physics, 2020
Using a novel quasi-relativistic wave equation, which can give precise results up to energies ~mc2, exact quantum mechanical solutions are found which corresponds to a particle with mass moving through one-dimensional piecewise constant potentials.

Foundations of the Quaternion Quantum Mechanics

open access: yesEntropy, 2020
We show that quaternion quantum mechanics has well-founded mathematical roots and can be derived from the model of the elastic continuum by French mathematician Augustin Cauchy, i.e., it can be regarded as representing the physical reality of elastic ...

Validation and administration of a conceptual survey on the formalism and postulates of quantum mechanics

open access: yesPhysical Review Physics Education Research, 2019
We developed and validated a conceptual survey that focuses on the formalism and postulates of quantum mechanics covered in upper-level undergraduate quantum mechanics courses. The concepts included in the quantum mechanics formalism and postulate survey
