Foundation and Application of Exact-WKB analysis

量子物理学・ナノサイエンス第399回セミナー

概要

The exact-WKB analysis, which is a mathematically rigorous extension of the WKB analysis, stands as one of the most powerful tools in the study of quantum mechanical systems. It offers significant improvements over semi-classical approximations, particularly in quantum systems where both perturbative and non-perturbative effects play a role. In this talk, after introducing Borel resummation, Stokes graphs and exact-WKB, I will discuss

（1）　the derivation of exact quantization conditions via the exact-WKB method,

（2）　its application to the Schwinger mechanism, and

（3) 　 its application to the Floquet system.
