Effective action for superfluid Fermi systems in the strong-coupling limit
N. Dupuis
We derive the low-energy effective action for three-dimensional superfluid Fermi systems in the strong-coupling limit, where superfluidity originates from Bose-Einstein condensatio…

Mott insulator to superfluid transition in the Bose-Hubbard model: a strong-coupling approach
K. Sengupta, N. Dupuis
We present a strong-coupling expansion of the Bose-Hubbard model which describes both the superfluid and the Mott phases of ultracold bosonic atoms in an optical lattice. By perfor…

Mott insulator to superfluid transition of ultracold bosons in an optical lattice near a Feshbach resonance
K. Sengupta, N. Dupuis
We study the phase diagram of ultracold bosons in an optical lattice near a Feshbach resonance. Depending on the boson density, the strength of the optical lattice potential and th…
