Quantum Phase Transition in Ultracold 87Rb Atom Gas with Radiant Field
Gang Chen, J. -Q. Liang, W. -M. Liu
A second-order quantum phase transition in two-species Bose-Einstein condensates of 87Rb atoms coupled by a quantized radiant field is revealed explicitly in terms of the energy sp…

Quantum phase transition of condensed bosons in optical lattices
Jun-Jun Liang, J. -Q. Liang, W. -M. Liu
In this paper we study the superfluid-Mott-insulator phase transition of ultracold dilute gas of bosonic atoms in an optical lattice by means of Green function method and Bogliubov…
