Strong Purcell effect of magnetic quasi-BICs in the dielectric metasurface
New Journal of Physics, 2023 The ultra-strong light field trapped in micro- and nanostructures, and derived from optical bound states in the continuums (BICs), provides a new platform for the facilitation of light–matter interactions.

Continuum of Bound States in a Non-Hermitian Model
2023 Photonics & Electromagnetics Research Symposium (PIERS), 2023 In a Hermitian system, bound states must have quantized energies, whereas extended states can form a continuum. We demonstrate how this principle fails for non-Hermitian systems, by analyzing non-Hermitian continuous Hamiltonians with an imaginary momentum and Landau-type vector potential. The eigenstates, which we call ``continuum Landau modes'' (CLMs)

Tunable bound states in the continuum in active metasurfaces of graphene disk dimers
Nanophotonics, 2023 Bound states in the continuum (BICs) in metasurfaces have lately attracted a great deal of attention stemming from their inherent (formally) divergent Q factors, which lead to an enhancement of light–matter interaction in two-dimensional geometries ...

Hyperparametric Oscillation via Bound States in the Continuum
Physical Review Letters, 2023 Optical hyperparametric oscillation based on the third-order nonlinearity is one of the most significant mechanisms to generate coherent electromagnetic radiation and produce quantum states of light. Advances in dispersion-engineered high-$Q$ microresonators allow for generating signal waves far from the pump and decrease the oscillation power ...

General Bound States in the Continuum in Momentum Space
Physical Review Letters, 2023 Polarization singularities including bound states in the continuum (BICs) and circularly polarized states have provided promising opportunities in the manipulation of light waves. Previous studies show that BICs in photonic crystal slabs are protected by $C_{2}T$ symmetry and hence normally exist on the high-symmetry lines of momentum space.
