Localization in microcavities revealed by phase-space non-Hermitian skin effect
Jung-Wan Ryu, Yong-Hoon Lee, Muhan Choi +2
Contrary to the semiclassical expectation for fully chaotic systems, localization of resonances is found to be a common feature in open microcavities. In spiral-shaped dielectric m…
Exceptional Classifications of Non-Hermitian Systems
Jung-Wan Ryu, Jae-Ho Han, Chang-Hwan Yi +2
Eigenstate coalescence in non-Hermitian systems is widely observed in diverse scientific domains encompassing optics and open quantum systems. Recent investigations have revealed t…
Bloch theorem dictated wave chaos in microcavity crystals
Chang-Hwan Yi, Hee Chul Park, Moon Jip Park
Universality class of wave chaos emerges in many areas of science, such as molecular dynamics, optics, and network theory. In this work, we generalize the wave chaos theory to cavi…
Classification of multiple arbitrary-order non-Hermitian singularities
Jung-Wan Ryu, Jae-Ho Han, Chang-Hwan Yi
We demonstrate general classifications of Riemann surface topology generated by multiple arbitrary-order exceptional points of quasi-stationary states. Our studies reveal all possi…
Strong interlayer coupling and stable topological flat bands in twisted bilayer photonic Moire superlattices
Chang-Hwan Yi, Hee Chul Park, Moon Jip Park
The moiré superlattice of misaligned atomic bilayers paves the way for designing a new class of materials with wide tunability. In this work, we propose a photonic analog of the mo…
Impact of non-Hermitian Mode interaction on Inter-cavity Light transfer
Hyeon-Hye Yu, Sunjae Gwak, Jinhyeok Ryu +4
Understanding inter-site mutual mode interaction in coupled physical systems is essential to comprehend large compound systems as this local interaction determines the successive m…
