The Hoyle state and its relatives

open access: yes, 2014
The Hoyle state and other resonances in the continuum above the 3 alpha threshold in 12C are studied in a microscopic cluster model. Whereas the Hoyle state is a very sharp resonance and can be treated reasonably well in bound state approximation, the ...

Electronic Structure in Gapped Graphene with Coulomb Potential

open access: yes, 2008
In this paper, we numerically study the bound electron states induced by long range Coulomb impurity in gapped graphene and the quasi-bound states in supercritical region based on the lattice model.

Catching the Bound States in the Continuum of a Phantom Atom in Graphene

open access: yes, 2015
We explore theoretically the formation of bound states in the continuum (BICs) in graphene hosting two collinear adatoms situated at different sides of the sheet and at the center of the hexagonal cell, where a phantom atom of a fictitious lattice ...

Continuum-continuum coupling and polarization potentials for weakly bound system

open access: yes, 2009
We investigate the influence of couplings among continuum states in collisions of weakly bound nuclei. For this purpose, we compare cross sections for complete fusion, breakup and elastic scattering evaluated by continuum discretized coupled channel ...

Boundary-localized many-body bound states in the continuum

open access: yesCommunications Physics
Bound states in the continuum (BICs), referring to spatially localized bound states with energies falling within the range of extended modes, have been extensively investigated in single-particle systems, leading to diverse applications in photonics ...

Two-vibron bound states lifetime in a one-dimensional molecular lattice coupled to acoustic phonons

open access: yes, 2003
The lifetime of two-vibron bound states in the overtone region of a one-dimensional anharmonic molecular lattice is investigated. The anharmonicity, introduced within an attractive Hubbard Hamiltonian for bosons, is responsible for the formation of bound

Super-Radiance: From Nuclear Physics to Pentaquarks

open access: yes, 2004
The phenomenon of super-radiance in quantum optics predicted by Dicke 50 years ago and observed experimentally has its counterparts in many-body systems on the borderline between discrete spectrum and continuum.

Robust multiresonant nonlocal metasurfaces by rational design

open access: yesNanophotonics
Dielectric metasurfaces supporting optical resonances have become a promising platform for quantum and nonlinear optics. However, resonant metasurfaces remain limited in their capacity to independently control the behavior of many distinct resonances ...

Evolution of Degenerate Pairs of Bound States in the Continuum With Broken Symmetry

open access: yesIEEE Photonics Journal
Bound states in the continuum (BICs) with exceptionally high quality factors ($Q$ factors) have become focal points in photonic device research, finding applications in nonlinear enhancement, laser generation, sensing, and beyond.
