A beyond mean field study of Bose gases in a double-well potential with a Feshbach resonance
Pérez Fernández, Pedro; Relaño, Armando; Dukelsky, Jorge; Arias Carrasco, José Miguel (American Institute of Physics, 2012)The Bose-Hubbard model coupled to a Feshbach resonance is studied. Quantum phase transitions are analyzed within a beyond ...
