Mott-Hubbard transition of bosons in optical lattices with two-body interactions
Mott-Hubbard transition of bosons in optical lattices with two-body interactions
Abstract
In this paper, based on the Bose-Hubbard model with two-body on-site interactions, we study the quantum phase transition between the superfluid state and the Mott-insulator state. With the decoupling approximation, we get the relation between the weak sup
