Relationship of the Gaussian width of Bose-condensed gas and the intensity of ID-optical lattices potential;

Interference of Bose-condensed gas in a 1D optical lattice;

A solution to the ground and single vortex states of Bose-condensed gas in an axially symmetric harmonic trap;

Superconductivity,magneto-thermal effect and Bose condensation developed in the low temperature physics of the 20th century are described brieflyIt is pointed that these discoveries and developments will come into practical use on a large scaleAll of these will give cryogenics a lot of favorable circumstances and chanllege

Basically superfluidity is a kind of quantum effect, that is Bose condensation.

Triangular vortex lattices in Bose-Einstein condensates;

The modulational instability(MI)of nonlinear coherent spin waves in an atomic spin chain of spinor Bose-Einstein condensates confined in an optical lattice is studied.

The theoretical investigation of quantum coherent atomic oscillations between two coupled Bose-Einstein condensates(BECs) is studied.

When considering the interaction between atoms,the Hamitonian operator of a system of two-mode light field interacting with Bose-Einstein condensate(BEC) of V-type three-level atoms is suggested within the rotating-wave approximation and Bogoliubov approximation.

In the framework of semi-classical theory,the author plots and analyzes the dynamical behaviors of Bose-Einstein condensate when initial phase difference is 0 and π,respectively,in a symmetric trap in weak interaction,without damping effects and periodical modulation.

When considering the interaction between atoms,the properties of quadrature squeezing of light field of two-model squeezing coherent light field interacting with atomic Bose-Einstein condensate is discussed.
