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: The tunneling current in Schottky barrier field-effect transistors (SBFETs) is calculated by two analytical approaches. The Wentzels-Kramer-Brillouin (WKB) approximation and a method based ...

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 ...

Abstract: In modern fabrication techniques, it is possible to fabricate nanostructure based semiconductor devices whose dimensions are much more comparable to the de Broglie wavelength of the electron ...

This code provides tools to trace the ray trajectories for Bogoliubov excitations on top of a polariton vortex flow. The mean field quantities are generated with ddGPE simulations. These rays are ...
