Tailoring Defects in Photonic Time Crystals for Coherent Energy Control
Dayeong Lee, Jongheon Yeo, Gitae Lee +3
Recent advances in time-varying photonics have revealed new degrees of freedom for manipulating optical states, arising from the distinctive nature of the temporal axis: causality…
Non-Hermitian stealthy hyperuniformity
Gitae Lee, Seungmok Youn, Ikbeom Lee +5
Symmetry-driven wave physics in open systems, exemplified by parity-time (PT) symmetry, has extended the landscape of crystalline phases in materials science to include gain-loss m…
Heterogeneous networks for phase-sensitive engineering of optical disordered materials
Seungmok Youn, Kunwoo Park, Ikbeom Lee +3
Heterogeneous networks provide a universal framework for extracting subsystem-level features of a complex system, which are critical in graph colouring, pattern classification, and…
Hypergraph modelling of wave scattering to speed-up material design
Kunwoo Park, Ikbeom Lee, Seungmok Youn +3
Hypergraphs offer a generalized framework for understanding complex systems, covering group interactions of different orders beyond traditional pairwise interactions. This modellin…
