One-Way Optical Transition based on Causality in Momentum Space
Sunkyu Yu, Xianji Piao, KyungWan Yoo +2
The concept of parity-time (PT) symmetry has been used to identify a novel route to nonreciprocal dynamics in optical momentum space, imposing the directionality on the flow of lig…

Low-dimensional optical chirality in complex potentials
Sunkyu Yu, Hyun Sung Park, Xianji Piao +2
Chirality is a universal feature in nature, as observed in fermion interactions and DNA helicity. Much attention has been given to chiral interactions of light, not only regarding…
