Painlev{é} singularity structure analysis of three component Gross-Pitaevskii type equations
T. Kanna, K. Sakkaravarthi, C. Senthil Kumar +2
In this paper, we have studied the integrability nature of a system of three coupled Gross-Pitaevskii type nonlinear evolution equations arising in the context of spinor Bose-Einst…
Matter-Wave Bright Solitons with a Finite Background in Spinor Bose-Einstein Condensates
Tetsuo Kurosaki, Miki Wadati
We investigate dynamical properties of bright solitons with a finite background in the F=1 spinor Bose-Einstein condensate (BEC), based on an integrable spinor model which is equiv…
Multicomponent Bright Solitons in F = 2 Spinor Bose-Einstein Condensates
Masaru Uchiyama, Jun'ichi Ieda, Miki Wadati
We study soliton solutions for the Gross--Pitaevskii equation of the spinor Bose--Einstein condensates with hyperfine spin F=2 in one-dimension. Analyses are made in two ways: by a…
Dark solitons in F=1 spinor Bose--Einstein condensate
Masaru Uchiyama, Jun'ichi Ieda, Miki Wadati
We study dark soliton solutions of a multi-component Gross--Pitaevskii equation for hyperfine spin F=1 spinor Bose--Einstein condensate. The interactions are supposed to be inter-a…
Inverse scattering method for square matrix nonlinear Schrödinger equation under nonvanishing boundary conditions
Jun'ichi Ieda, Masaru Uchiyama, Miki Wadati
Matrix generalization of the inverse scattering method is developed to solve the multicomponent nonlinear Schrödinger equation with nonvanishing boundary conditions. It is shown th…
Exact Analysis of Delta-Function Attractive Fermions and Repulsive Bosons in One-Dimension
Toshiaki Iida, Miki Wadati
The Gaudin integral equation for the ground state of a one-dimensional delta-function attractive spin-1/2 fermions is solved in the form of power series. The first few terms of the…
