Ladder Operators in Repulsive Harmonic Oscillator with Application to the Schwinger Effect
Kenichi Aouda, Naohiro Kanda, Shigefumi Naka +1
The ladder operators in harmonic oscillator are a well-known strong tool for various problems in physics. In the same sense, it is sometimes expected to handle the problems of repu…
