In this study, we analyze the bound-state energy spectrum of quark-antiquark systems using the semiclassical WKB approximation. We consider the Cornell potential, which combines a linear confinement ...

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 ...

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.
