Confinement-induced resonances

V Dunjko, MG Moore, T Bergeman… - Advances in Atomic …, 2011 - Elsevier
Confinement-induced resonances (CIRs) arise when particle scattering takes place in the
presence of an external potential that spatially confines the motion of the particles. One finds …

Quasi-integrability and nonlinear resonances in cold atoms under modulation

R Gupta, M Jain, SR Jain - Royal Society Open Science, 2024 - royalsocietypublishing.org
Quantum dynamics of a collection of atoms subjected to phase modulation has been
carefully revisited. We present an exact analysis of the evolution of a two-level system …

Vector solitons and different scenarios of universal dynamics in a spin-1 Bose-Einstein condensate

S Lannig - 2022 - archiv.ub.uni-heidelberg.de
Solitons are fascinating non-dispersive solutions to non-linear systems, which appear in
various scenarios across nature. Because of their stability and longevity these excitations …

Dimensional reduction of a binary Bose-Einstein condensate in mixed dimensions

LE Young-S, L Salasnich, SK Adhikari - Physical Review A—Atomic, Molecular …, 2010 - APS
We present effective reduced equations for the study of a binary Bose-Einstein condensate
(BEC), where the confining potentials of the two BEC components have distinct asymmetry …

Minlos–Faddeev regularization of zero-range interactions in the three-body problem

OI Kartavtsev, AV Malykh - JETP Letters, 2022 - Springer
To regularize the three-body problem, Minlos and Faddeev suggested a modification of zero-
range model, which diminishes interaction at the triple-collision point. The analysis reveals …

Two-component spin mixtures

G Lamporesi - arXiv preprint arXiv:2304.03711, 2023 - arxiv.org
The high degree of control on ultracold gases allows us to precisely manipulate their internal
state. When the gas is made of atoms in two different internal states, it can be considered as …

Tight-binding Kondo model and spin-exchange collision rate of alkaline-earth-metal atoms in a mixed-dimensional optical lattice

R Zhang, P Zhang - Physical Review A, 2020 - APS
We study the two-body problem of ultracold fermionic alkaline-earth-metal-(like) atoms in the
electronic S 0 1 state (g-state) and P 0 3 state (e-state) which are confined in a quasi-one …

Analytical approach to atomic multichannel collisions in tight harmonic waveguides

B Heß, P Giannakeas, P Schmelcher - Physical Review A, 2015 - APS
We perform an analytical investigation in the framework of generalized K-matrix theory of the
scattering problem in tight isotropic and harmonic waveguides allowing for several open …

U (3) artificial gauge fields for cold atoms

YX Hu, C Miniatura, D Wilkowski, B Gremaud - Physical Review A, 2014 - APS
We propose to generate an artificial non-Abelian U (3) gauge field by using a two-tripod
scheme, namely, two tripod configurations sharing a common ground-state level and driven …

Quantitative study of two-and three-dimensional strong localization of matter waves by atomic scatterers

M Antezza, Y Castin, DAW Hutchinson - Physical Review A—Atomic, Molecular …, 2010 - APS
We study the strong localization of atomic matter waves in a disordered potential created by
atoms pinned at the nodes of a lattice, for both three-dimensional (3D) and two-dimensional …
