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 ...

Circularly Polarized States Spawning from Bound States in the Continuum [PDF]
Physical Review Letters, 2019 Bound states in the continuum in periodic photonic systems like photonic crystal slabs are proved to be accompanied by vortex polarization singularities on the photonic bands in the momentum space. The winding structures of polarization states not only widen the field of topological physics but also show great potential that such systems could be ...

Bound States in the Continuum in Compact Acoustic Resonators [PDF]
Physical Review Letters, 2022 We reveal that finite-size solid acoustic resonators can support genuine bound states in the continuum (BICs) completely localized inside the resonator. The developed theory provides the multipole classification of such BICs in the resonators of various shapes.

Topological Subspace-Induced Bound State in the Continuum [PDF]
Physical Review Letters, 2017 We propose and experimentally realize a new kind of bound states in the continuum (BICs) in a class of systems constructed by coupling multiple identical one-dimensional chains, each with inversion symmetry. In such systems, a specific separation of the Hilbert space into a topological and a nontopological subspace exists.

Double-Strip Array-Based Metasurfaces with BICs for Terahertz Thin Membrane Detection
Micromachines, 2023 A double-strip array-based metasurface that supports the sharp quasi-bound states in the continuum (quasi-BICs) is demonstrated in terahertz regions.

Bound states in the continuum: localization of Dirac-like fermions
, 2014 We report the formation of bound states in the continuum for Dirac-like fermions in structures composed by a trilayer graphene flake connected to nanoribbon leads. The existence of this kind of localized states can be proved by combining local density of

Asymmetric tetramer metasurface sensor governed by quasi-bound states in the continuum
Nanophotonics, 2023 Asymmetric metasurfaces supporting quasi-bound states in the continuum (BICs) with high Q-factors and strong light–matter interaction properties are attractive platforms for label-free biosensing applications.

Bound states in the continuum in open acoustic resonators
, 2015 We consider bound states in the continuum (BSC) or embedded trapped modes in two- and three-dimensional acoustic axisymmetric duct-cavity structures. We demonstrate numerically that under variation of the length of the cavity multiple BSCs occur due to ...

Level Density in the Complex Scaling Method [PDF]
, 2005 It is shown that the continuum level density (CLD) at unbound energies can be calculated with the complex scaling method (CSM), in which the energy spectra of bound states, resonances and continuum states are obtained in terms of $L^2$ basis functions ...
