Hidden quantum-classical correspondence in chaotic billiards revealed by mutual information
Kyu-Won Park, Soojoon Lee, Kabgyun Jeong
Avoided level crossings, commonly associated with quantum chaos, are typically interpreted as signatures of eigenstate hybridization and spatial delocalization, often viewed as erg…

Entropic comparison of Landau-Zener and Demkov interactions in the phase space of a quadrupole billiard
Kyu-Won Park, Juman Kim, Jisung Seo +3
We investigate two types of avoided crossings in a chaotic billiard within the framework of information theory. The Shannon entropy in the phase space for the Landau--Zener interac…
