Coexistence of two kinds of superfluidity in Bose-Hubbard model with density-induced tunneling at finite temperatures

A. Krzywicka, T. P. Polak

With use of the U(1) quantum rotor method in the path integral effective action formulation, we have confirmed the mathematical similarity of the phase Hamiltonian and of the exten…
