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.

Chemistry and Quantum Mechanics [PDF]

open access: yesJournal of the Chinese Chemical Society, 2021
Of quantum physics, quantum chemistry and quantum mechanics, the latter is least useful for both chemical education and the practice of chemistry as a science concerned with the reactions and properties of chemical substances. We show that quantum mechanics must be viewed as a collection of methods, numbering at least thirteen, that one might ...

Realism and objectivism in quantum mechanics [PDF]

open access: yes, 2012
The present study attempts to provide a consistent and coherent account of what the world could be like, given the conceptual framework and results of contemporary quantum theory. It is suggested that standard quantum mechanics can, and indeed should, be

Quantum mechanics on the cylinder [PDF]

open access: yesJournal of Optics B: Quantum and Semiclassical Optics, 2003
A new approach to deformation quantization on the cylinder considered as phase space is presented. The method is based on the standard Moyal formalism for R^2 adapted to (S^1 x R) by the Weil--Brezin--Zak transformation. The results are compared with other solutions of this problem presented by Kasperkovitz and Peev (Ann. Phys. vol. 230, 21 (1994)0 and

Emergent Quantum Mechanics: David Bohm Centennial Perspectives

open access: yesEntropy, 2019
Emergent quantum mechanics (EmQM) explores the possibility of an ontology for quantum mechanics. The resurgence of interest in realist approaches to quantum mechanics challenges the standard textbook view, which represents an operationalist approach. The

Quantum Information in Geometric Quantum Mechanics [PDF]

open access: yes, 2011
A fundamental starting point in quantum information theory is the consideration of the von Neumann entropy and its generalization to relative quantum entropies.

Framework for understanding the patterns of student difficulties in quantum mechanics

open access: yesPhysical Review Special Topics. Physics Education Research, 2015
[This paper is part of the Focused Collection on Upper Division Physics Courses.] Compared with introductory physics, relatively little is known about the development of expertise in advanced physics courses, especially in the case of quantum mechanics ...

Randomness in Classical Mechanics and Quantum Mechanics [PDF]

open access: yesFoundations of Physics, 2010
The Copenhagen interpretation of quantum mechanics assumes the existence of the classical deterministic Newtonian world. We argue that in fact the Newton determinism in classical world does not hold and in classical mechanics there is fundamental and irreducible randomness.

DIRAC AND HAMILTON

open access: yesActa Polytechnica, 2014
Dirac devised his theory of Quantum Mechanics and recognised that his operators resembled the canonical coordinates of Hamiltonian Mechanics. This gave the latter a new lease of life.
