Rigorous results of phase transition theory in lattice boson models
D. P. Sankovich Steklov Mathematical Institute of Russian Academy of Sciences, Moscow, Russia
Abstract:
Quantum systems of particles obeying Bose statistics and moving in $d$-dimensional lattices are studied. The original Bose–Hubbard Hamiltonian is considered, together with model systems related to this Hamiltonian: the Bose–Hubbard model with exchange interaction of infinite radius and the Bose–Hubbard model with infinite interaction potential. Rigorous results concerning the proof of the existence of Bose condensation and a phase transition to the Mott insulator state in these systems are presented.
