Quantum criticality of a Bose gas in an optical lattice near the Mott transition
A. Rancon, N. Dupuis
We derive the equation of state of bosons in an optical lattice in the framework of the Bose-Hubbard model. Near the density-driven Mott transition, the expression of the pressure…
Infrared behavior of interacting bosons at zero temperature
N. Dupuis, A. Rancon
We review the infrared behavior of interacting bosons at zero temperature. After a brief discussion of the Bogoliubov approximation and the breakdown of perturbation theory due to…

Nonperturbative renormalization-group approach to strongly-correlated lattice bosons
A. Rancon, N. Dupuis
We present a nonperturbative renormalization-group approach to the Bose-Hubbard model. By taking as initial condition of the renormalization-group flow the (local) limit of decoupl…
