Magnetic graphs for cavity quantum electrodynamics
Sunkyu Yu, Xianji Piao, Namkyoo Park
Strengthening light-matter coupling has become a central challenge in cavity quantum electrodynamics (QED), enabling ultrafast gate operations, qubit protection, and deterministic…
Mapping open quantum dynamics onto graphs
Kyuho Kim, Dayeong Lee, Seungkyun Park +3
Graph-theoretic frameworks have been widely employed in quantum physics to address the high-dimensional complexity of quantum systems. Although open quantum dynamics incorporates s…
Multi-objective design of photon blockade for bright single-photon sources
Sunkyu Yu, Xianji Piao, Namkyoo Park
High-quality single-photon sources, realized through saturable emitters, photon blockade, or heralded pair generation, are indispensable building blocks for photonic quantum platfo…
Topological heavy-tailed networks
Sunkyu Yu, Xianji Piao, Namkyoo Park
Although two-dimensional periodic structures have functioned as the primary platform for exploring topological phenomena, recent advances have substantially expanded this research…
Fully programmable slow light based on a spinor representation of generalized coupled-resonator-induced transparency
Seungkyun Park, Beomjoon Chae, Hyungchul Park +3
Electromagnetically induced transparency (EIT), arising from quantum interference in coherently driven atomic systems, has inspired a variety of photonic analogues, such as coupled…
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…
