Recent advances in nano-technology have opened up new ways to pioneer various attractive devices based on light-electron interaction, such as plasmonic devices, quantum dot, and so on. Computational treatments for the devices frequently tend to be intricate since those natures are characterized by some combined physical rules, namely multi-physics. Authors have proposed and demonstrated Maxwell-Schrödinger multi-physics simulation to solve such problems, particularly about light-electron interaction, where the novel simulation employs both classical and quantum theories to realize precise and efficient computation.
The present paper introduces recent progresses of our works relying on the Maxwell-Schrödinger multi-physics simulation: (A) an enormous amount of electrons confined in a thin film, (B) a single electron confined in a thin tube. We will focus on and clarify the electron dynamics for those two cases which are strongly affected by cooperative effects with light.
