Bound states in the continuum (BICs) have been extensively investigated in single-particle systems, leading to diverse applications in photonics, acoustics, and other classical-wave systems. Here, the authors propose a type of interaction-induced many-body BICs at boundaries and...
Such bound states are shown to have a large effect on scattering of both Fock and coherent state wavepackets, especially in the intermediate coupling strength regime. We compare the statistics of the transmitted light with a coherent state having the same mean photon number: as the interaction ...
The Continuum Shell Model is a powerful theoretical tool for analysis of many-body dynamics embedded in the continuum. Here we formulate the method and use an example of a realistic shell model calculation for oxygen isotopes to demonstrate the seamless transition from bound states to resonances ...
On bound states in the continuum of N-body systems and the virial theorem We prove generalized versions of the quantum mechanical virial theorem and apply them to the investigation of the spectrum of N body Hamiltonians. We show,... S Albeverio - 《Annals of Physics》 被引量: 87发表: 19...

The rotationless, vibrational states of two weakly bound triatomic species are calculated using a variational expansion over multicentred Gaussian functions (the DGF method described in the main text) and corrections are introduced by using the three-body potentials vis à vis the sum-of-potentials ...
Unlike these conventional excitons formed from extended Bloch states4,5,6,7,8,9, excitonic bound states from intrinsically many-body localized states are rare. Here we show that a spin–orbit-entangled exciton state appears below the Néel temperature of 150 kelvin in NiPS3, an antiferromagnetic...
Then, since a nonzero Chern number is encoded in the continuum topological response theory as a Chern-Simons term93, it might be expected that RSIs appear as well. In the presence of crystalline symmetries, the response theory includes Wen-Zee-type terms14,19,31,94,95,96,97,98,99,100,...
Let us assume that the impurity either lives in the continuum (such that effectively the impurity lattice constant a-0 vanishes) or that the unit cell of the impurity lattice fits into the magnetic unit cell of the host many-body system an integer number of times in a commensurable way. ...
