Solitons in Bose-Einstein condensates trapped in a double-well potential
(Elsevier B.V., 2004-02-01)
We investigate, analytically and numerically, families of bright solitons in a system of two linearly coupled nonlinear Schrodinger/Gross-Pitaevskii equations, describing two Bose-Einstein condensates trapped in an asymmetric ...
Gap solitons in a spin-orbit-coupled bose-einstein condensate
(2013-08-07)
We report a diversity of stable gap solitons in a spin-orbit-coupled Bose-Einstein condensate subject to a spatially periodic Zeeman field. It is shown that the solitons can be classified by the main physical symmetries ...
Dynamics of bright matter wave solitons in a Bose-Einstein condensate
(2005-09-10)
Recent experimental and theoretical advances in the creation and description of bright matter wave solitons are reviewed. Several aspects are taken into account, including the physics of soliton train formation as the ...
Formation of bright solitons and soliton trains in a fermion-fermion mixture by modulational instability
(Iop Publishing Ltd, 2007-03-16)
We employ a time- dependent mean- field- hydrodynamic model to study the generation of bright solitons in a degenerate fermion - fermion mixture in a cigar- shaped geometry using variational and numerical methods. Due to ...
Bright solitons and soliton trains in a fermion-fermion mixture
(Springer, 2006-11-01)
We use a time-dependent dynamical mean-field-hydrodynamic model to predict and study bright solitons in a degenerate fermion-fermion mixture in a quasi-one-dimensional cigar-shaped geometry using variational and numerical ...
Insulator-to-metal transition driven by clustering of solitons in polyacetylene
(1997-03-15)
It's believed that the simple Su-Schrieffer-Heeger Hamiltonian can not predict the insulator to metal transition of transpolyacetylene (t-PA). The soliton lattice configuration at a doping level y=6% still has a semiconductor ...
Dissipation-managed soliton in a quasi-one-dimensional Bose-Einstein condensate
(Iop Publishing Ltd, 2006-11-01)
We use the time-dependent mean-field Cross-Pitaevskii equation to study the formation of a dynamically-stabilized dissipation managed bright soliton in a quasi-one dimensional Bose-Einstein condensate (BEC). Because of ...
Grassmannian and bosonic Thirring models with jump defects
(Springer, 2011-02-01)
In this paper we discuss the Lax formulation of the Grassmannian and Bosonic Thirring models in the presence of jump defects. For the Grassmannian case, the defect is described by Backlund transformation which is responsible ...
Black soliton in a quasi-one-dimensional trapped fermion-fermion mixture
(Wiley-Blackwell, 2006-12-01)
Employing a time dependent mean-field-hydrodynamic model we study the generation of black solitons in a degenerate fermion-fermion mixture in a cigar-shaped geometry using variational and numerical solutions. The black ...
