Absence of bound states implies non-negativity of the scattering length
Absence of bound states non-negativity of the scattering length Mathematical Physics
2012/4/18
We show that bosons interacting via pair potentials with negative scattering length form bound states for a suitable number of particles. In other words, the absence of many-particle bound states of a...
Scaling and universality in two dimensions: three-body bound states with short-ranged interactions
two dimensions three-body bound states short-ranged interactions Quantum Gases
2011/10/8
Abstract: The momentum space zero-range model is used to investigate universal properties of three interacting particles confined to two dimensions. The pertinent equations are first formulated for a ...
Bound states of PT-symmetric separable potentials
PT-symmetric separable potentials High Energy Physics - Theory
2011/9/30
Abstract: All of the PT-symmetric potentials that have been studied so far have been local. In this paper nonlocal PT-symmetric separable potentials of the form $V(x,y)=i\epsilon[U(x)U(y)-U(-x)U(-y)]$...
Bound states in the radiation continuum and a resonant generation of second harmonics in double arrays of subwavelength dielectric cylinders
Bound states radiation continuum subwavelength dielectric cylinder second harmonics
2011/8/24
Abstract: A nonlinear electromagnetic scattering problem is studied for two parallel periodic arrays of dielectric cylinders with a second order nonlinear susceptibility. For a wide range of values of...
Novel Bound States Treatment of the Two Dimensional Schrodinger Equation with Pseudocentral Plus Multiparameter Noncentral Potential
Pseudocentral potentials noncentral potential two dimensional Schrodinger equation
2011/7/28
Abstract: By converting the rectangular basis potential V(x,y) into the form as V(r)+V(r, phi) described by the pseudo central plus noncentral potential, particular solutions of the two dimensional Sc...

Quasi-bound states in the continuum: a dynamical coupled-channel calculation of axial-vector charmed mesons
Quasi-bound coupled-channel axial-vector
2011/9/14
Masses and widths of the charmed axial-vector mesons D1(2420), D1(2430), Ds1(2536), and Ds1(2460) are calculated nonperturbatively in the Resonance-Spectrum-Expansion model, by coupling various open a...
Conformal Mapping and Bound States in Bent Waveguides
Conformal Mapping Bent Waveguides Quantum Physics
2010/11/8
Is it possible to trap a quantum particle in an open geometry? In this work we deal with the boundary value problem of the stationary Schroedinger (or Helmholtz) equation within a waveguide with strai...
Effect of quasi-bound states on coherent electron transport in twisted nanowires
quasi-bound states coherent electron transport twisted nanowires
2010/11/8
Quantum transmission spectra of a twisted electron waveguide expose the coupling between traveling and quasi-bound states. Through a direct numerical solution of the open-boundary Schr\"odinger equati...
A relativistic coupled-channel formalism for electromagnetic form factors of 2-body bound states
Relativistic quantum mechanics Few-body systems Electromagnetic structure
2011/1/6
We discuss a Poincar´e invariant coupled-channel formalism which is based on the point-form of relativistic quantum mechanics.
