We study higher order solutions of Lieb–Liniger integral equation for a one-dimensional δ -function Bose gas. By use of the power series expansion method, the integral equation is solved and the correction terms which improve the Bogoliubov theory

We investigate the coupled Gross–Pitaevskii equation describing the dynamics of two hyperfine states of Bose–Einstein condensates and deduce the integrability condition for the propagation of bright vector solitons. We show how the transient trap

One-dimensional pulse propagations in the electromagnetically induced media are investigated. The Maxwell-Bloch equations for a three-level medium are simplified with the approximations of slowly varying amplitudes, negligible irreversible relaxation

We investigate the ground-state properties of a one-dimensional spin-1/2 fermionic atoms interacting through the attractive δ-function potential in an external magnetic field. By the thermal Bethe ansatz method, the integral equations for the dresse

The dispersion properties of three-dimensional electrostatic waves in a nonuniform electron-positron (EP) magnetoplasma are analyzed. A new dispersion relation is derived by use of the electron and positron density responses arising from the electron

We review the recently studied soliton dynamics of the hyperfine spin F=1 spinor Bose–Einstein condensate in a one-dimensional uniform system. The characters of one-soliton states and the behavior of two-soliton collision are briefly described.

Nonlinear wave propagations in spinor Bose–Einstein condensates confined strongly along an axial direction are studied. Due to the confinement induced effects, there exist a variety of soliton solutions with the magnetic properties.

We study a one-dimensional integrable system of N spin-1/2 fermions with attractive δ-function interaction at zero temperature. The Gaudin integral equation describing the ground state with arbitrary spin polarization is solved in the form of power
