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 ...
Laplacian flow of homogeneous G 2 -structures and its solitons
(London Mathematical Society, 2017-03)
We use the bracket flow/algebraic soliton approach to study the Laplacian flow of G2-structures and its solitons in the homogeneous case. We prove that any homogeneous Laplacian soliton is equivalent to a semi-algebraic ...
Hitchin–Thorpe inequality and Kaehler metrics for compact almost Ricci soliton
(Brasil, 2013)
The purpose of this paper is to prove a Hitchin–Thorpe inequality for a four-dimensional compact almost Ricci soliton. Moreover, we prove that under a suitable integral condition, a four-dimensional compact almost Ricci ...
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 ...

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 ...
Stable multi-peak vector solitons in spin–orbit coupled spin-1 polar condensates
(2020-04-01)
We demonstrate the formation of multi-peak three-component stationary stripe vector solitons in a quasi-one-dimensional spin–orbit-coupled hyper-fine spin F=1 polar Bose–Einstein condensate. The present investigation is ...
Spontaneous spatial order in two-dimensional ferromagnetic spin-orbit coupled uniform spin-1 condensate solitons
(2021-02-05)
We demonstrate spontaneous spatial order in stripe and super-lattice solitons in a Rashba spin-orbit (SO) coupled spin-1 uniform quasi-two-dimensional (quasi-2D) ferromagnetic Bose-Einstein condensate (BEC). For weak SO ...
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 ...
