Observation of an exceptional point in a chaotic optical microcavity
Sang-Bum Lee, Juhee Yang, Songky Moon +5
We present spectroscopic observation of an exceptional point or the transition point between diabatic crossing and avoided crossing of neighboring quasi-eigenmodes in a chaotic opt…

Quasi-Eigenstate Evolution in Open Chaotic Billiards
Sang-Bum Lee, Juhee Yang, Songky Moon +5
We experimentally studied evolution of quasi-eigenmodes as classical dynamics undergoing a transition from being regular to chaotic in open quantum billiards. In a deformation-vari…
