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.

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 ...

We extend the WKB method for the computation of cosmological perturbations during inflation beyond leading order and provide the power spectra of scalar and tensor perturbations to second order in the ...

Abstract: Rigorous pointwise asymptotics are established for semiclassical soliton ensembles (SSEs) of the focusing nonlinear Schrödinger equation using techniques of asymptotic analysis of matrix ...

Note: The article usage is presented with a three- to four-day delay and will update daily once available. Due to ths delay, usage data will not appear immediately following publication. Citation ...

Abstract: A new formulation of scattering and propagation problems has been developed using Green's functions with essentially correct local behavior. This formulation, which is exact, yields the ...

A generalization of the modified WKB method proposed by Good and by Rosen and Yennie as applied to the scattering problem is presented. In the formulation of this problem the main equation connects ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

Frequency-domain full-wave solutions to the cold-plasma problem have become ubiquitous in the study of radio frequency power in fusion plasmas. However, recent efforts at extreme levels of geometric ...
