The minimum-uncertainty coherent states empirically provide an approximation to the motion of a classical particle. This can be understood conceptually. One can obtain a relationship between the WKB ...

Department of Applied Physics, Tafila Technical University, Tafila, Jordan. The quantization of constrained systems has been started by Dirac [1] . The quantization of constrained systems has been ...

This repository contains Python code for the WKB (Wentzel-Kramers-Brillouin) approximation, which is a method used in quantum mechanics to approximate wave functions in regions where they vary slowly.

Particle production by slow-changing gravitational fields is usually described using quantum field theory in curved spacetime. Calculations require a definition of the vacuum state, which can be given ...

Abstract: Layered superconductors represent unusual materials that invoke the interest of many researchers. To describe electrodynamics in layered superconductors, well-known coupled sine-Gordon ...
