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…
Programmable photonic unitary circuits for light computing
Kyuho Kim, Kunwoo Park, Hyungchul Park +3
Unitarity serves as a fundamental concept for characterizing linear and conservative wave phenomena in both classical and quantum systems. Developing platforms that perform unitary…
