The Mass Spectrum of a Static Adjoint Particle [PDF]

, 1997
The bound states of fermions in the adjoint representation are of interest in supersymmetric models. We investigate the energy spectrum of the simplest -- the gluino-gluon bound states -- on several lattices in the quenched approximation. We use a static

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.

New method for extracting quasi-bound states from the continuum

, 2007
A new parameter-free method is proposed for treatment of single-particle resonances in the real-energy continuum shell model. This method yields quasi-bound states embedded in the continuum which provide a natural generalization of weakly bound single ...

Excitonic states of an impurity in a Fermi gas [PDF]

, 2015
We study excitonic states of an atomic impurity in a Fermi gas, i.e., bound states consisting of the impurity and a hole. Previous studies considered bound states of the impurity with particles from the Fermi sea where the holes only formed part of the ...

Simulation Analysis of Microwave Metasurface Sensing Based on Bound States in the Continuum

Photonics
High-sensitivity microwave sensing plays a vital role in material characterization and nondestructive testing, with its performance being largely determined by the quality factor (Q factor) of the sensing structure.

Active angular tuning and switching of Brewster quasi bound states in the continuum in magneto-optic metasurfaces

Nanophotonics, 2021
Bound states in the continuum (BICs) emerge throughout physics as leaky/resonant modes that remain, however, highly localized. They have attracted much attention in photonics, and especially in metasurfaces.

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

Topological nature of bound states in the radiation continuum [PDF]

, 2014
Bound states in the continuum (BICs) are unusual solutions of wave equations describing light or matter: they are discrete and spatially bounded, but exist at the same energy as a continuum of states which propagate to infinity. Until recently, BICs were

Bound states in the continuum in periodic structures with structural disorder

Nanophotonics, 2021
We study the effect of structural disorder on the transition from the bound states in the continuum (BICs) to quasi-BICs by the example of the periodic photonic structure composed of two layers of parallel dielectric rods.

Active quasi-BIC optical vortex generators for ultrafast switching

New Journal of Physics, 2022
The Pancharatnam–Berry phase induced by the winding topology of polarization around a vortex singularity at bound states in the continuum (BIC) provides a unique approach to optical vortex (OV) generation.
