Bound valley edge states in the continuum
Optics Letters, 2022Topological valley photonics provides a unique way to manipulate the flow of light. In general, valley edge states that exhibit unidirectional propagation and are immune to defects and disorders could be realized at the interface between two valley photonic crystals with opposite valley Chern numbers.

Bound States in the Continuum in Photonics
Physical Review Letters, 2008With examples of two parallel dielectric gratings and two arrays of thin parallel dielectric cylinders, it is shown that the interaction between trapped electromagnetic modes can lead to scattering resonances with practically zero width. Such resonances are the bound states in the radiation continuum first discovered in quantum systems by von Neumann ...

Generation of bound states in a continuum
Physical Review A, 1990'(hereafter referred to as LR) published a pair of papers that examined the conditions under which discrete states can exist within the energy range occupied by a continuum. They demonstrate the somewhat surprising result that under rather general conditions on two or more external fields, there exists an equal number of bound states within the energy ...

Plexcitonic Quasi‐Bound States in the Continuum
Small, 2021AbstractEnhancing light‐matter interactions is fundamental to the advancement of nanophotonics and optoelectronics. Yet, light diffraction on dielectric platforms and energy loss on plasmonic metallic systems present an undesirable trade‐off between coherent energy exchange and incoherent energy damping.

Physical Review A, 1975
Quantum-mechanical examples have been constructed of local potentials with bound eigenstates embedded in the dense continuum of scattering states. The method employed corrects and extends a procedure invented by von Neumann and Wigner. Cases are cited whereby deformation of the local potential causes the continuum bound state to move downward through ...

Radial bound states in the continuum
Conference on Lasers and Electro-Optics, 2021We experimentally demonstrate a new platform for enhanced light-matter interaction and sensing based on radial bound states in the continuum, which are supported in rings of symmetry-broken dielectric resonators with an ultracompact footprint.

Reply to ‘‘Generation of bound states in a continuum’’
Physical Review A, 1990It is recognized that the preceding Comment by Glosson and Cantrell [Phys. Rev. A 41, 2898 (1990)] corrects an algebraic error present in our two previous papers [Lami and Rahman, Phys. Rev. A 33, 782 (1986); 34, 3908 (1986)] (concerning a nonessential point).

Physical realization of bound states in the continuum
Physical Review A, 1985We show within the framework of quantum-defect theory that bound states in the continuum (BIC) can occur in systems of at least three coupled Coulombic channels due to the interference of resonances belonging to different channels. As a physical realization of such BIC, we discuss the Schr\"odinger equation describing a hydrogen atom in a uniform ...

On the bound states in the continuum
Physics Letters A, 1977Abstract It is shown that a special case of the amplitude modulation method of von Neumann and Wigner for constructing local potentials and normalizable wavefunctions of bound states in the continuum, and the formal use of the Gelfand-Levitan theory lead to the same results. A possible application for complex-energy resonance models is indicated.
