Room-temperature amplified transduction of infrared to visible photons
Gibeom Son, Songky Moon, Seunghoon Oh +2
Frequency transduction, which converts photons from one energy level to another, provides a way to bridge different quantum devices. The frequency transduction has been studied acr…
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…
Indicators of wavefunction (de)localization in the avoided crossing in a quadrupole cavity
Kyu-Won Park, Juman Kim, Jisung Seo +2
We study the relation between wavefunction (de)localization and the avoided crossing in a quadrupole billiard. We employ the inverse participation ratio, the Renyi entropy and the…
Behavior of Shannon entropy around an exceptional point in an open microcavity
Kyu-Won Park, Jinuk Kim, Songky Moon +1
We have investigated the Shannon entropy around an exceptional point (EP) in an open elliptical microcavity as a non-Hermitian system. The Shannon entropy had an extreme value at t…
Shannon entropy as an indicator of spatial resolution for morphology of mode pattern in dielectric microcavity
Kyu-Won Park, SongKy Moon, JinUk Kim
We present the Shannon entropy as an indicator of spatial resolution for morphology of resonance mode pattern in dielectric micro cavity. We obtain two types of optimized mesh poin…
Non-Hermiticity and conservation of orthogonal relation in dielectric microcavity
Kyu-Won Park, Songky Moon, Hyunseok Jeong +2
Non-Hermitian properties of open quantum systems and their applications have attracted much attention in recent years. While most of the studies focus on the characteristic nature…
