Bound states in the continuum [PDF]

Nature Reviews Materials, 2016
Bound states in the continuum (BICs) are waves that remain localized even though they coexist with a continuous spectrum of radiating waves that can carry energy away. Their very existence defies conventional wisdom.

Bound states in the continuum and exceptional points in dielectric waveguide equipped with a metal grating

New Journal of Physics, 2020
Bound states in the continuum (BICs) and exceptional points (EPs) have been the subjects of recent intensive research as they exhibit exotic phenomena that are significant for both fundamental physics and practical applications.

Label-free DNA biosensing by topological light confinement

Nanophotonics, 2021
Large-area and transparent all-dielectric metasurfaces sustaining photonic bound states in the continuum (BICs) provide a set of fundamental advantages for ultrasensitive biosensing.

Kerker Effects and Bound States in the Continuum in PT-Symmetric Dielectric Metasurfaces

IEEE Photonics Journal, 2022
We investigate the light transmission and reflection spectra of parity-time (PT) symmetric dielectric metasurfaces composed of high refractive index nanostructures with in-plane gain-loss modulation through the scattering matrix and semianalytical ...

Passive nonreciprocal transmission and optical bistability based on polarization-independent bound states in the continuum

Nanophotonics, 2023
Free-space nonreciprocal transmission is a crucial aspect of modern optics devices. The implementation of nonreciprocal optical devices through optical nonlinearity has been demonstrated.

Anyonic bound states in the continuum

Communications Physics, 2023
Bound states in the continuum (BICs), which are spatially localized states with energies lying in the continuum of radiating modes, are discovered both in single- and few-body systems with suitably engineered spatial potentials and particle interactions.

Bound states in the continuum driven by AC fields [PDF]

, 2013
We report the formation of bound states in the continuum driven by AC fields. This system consists of a quantum ring connected to two leads. An AC side-gate voltage controls the interference pattern of the electrons passing through the system.

ac Josephson effect in asymmetric superconducting quantum point contacts [PDF]

, 2004
We investigate ac Josephson effects between two superconductors connected by a single-mode quantum point contact, where the gap amplitudes in the two superconductors are unequal.

Universal coupled theory for metamaterial bound states in the continuum

New Journal of Physics, 2021
In this paper, we present a novel universal coupled theory for metamaterial bound states in the continuum (BIC) or quasi-bound states in the continuum (quasi-BIC) which provides ultra-high Q resonance for metamaterial devices.
