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 ...

In this work, we develop and apply the WKB approximation to several examples of noncommutative quantum cosmology, obtaining the time evolution of the noncommutative universe, this is done starting ...

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.

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