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…
