Quantum phases in a resonantly-interacting Bose-Fermi mixture
D. B. M. Dickerscheid, D. van Oosten, E. J. Tillema +1
We consider a resonantly-interacting Bose-Fermi mixture of K and Rb atoms in an optical lattice. We show that by using a red-detuned optical lattice the mixture can b…
Feshbach resonances in an optical lattice
D. B. M. Dickerscheid, U. Al Khawaja, D. van Oosten +1
We present the theory for ultracold atomic gases in an optical lattice near a Feshbach resonance. In the single-band approximation the theory describes atoms and molecules which ca…
Inelastic light scattering from a Mott insulator
D. Van Oosten, D. B. M. Dickerscheid, P. van der Straten +1
We propose to use Bragg spectroscopy to measure the excitation spectrum of the Mott insulator state of an atomic Bose gas in an optical lattice. We calculate the structure factor o…
Ultracold atoms in optical lattices
D. B. M. Dickerscheid, D. van Oosten, P. J. H. Denteneer +1
Bosonic atoms trapped in an optical lattice at very low temperatures, can be modeled by the Bose-Hubbard model. In this paper, we propose a slave-boson approach for dealing with th…
Mott insulators in an optical lattice with high filling factors
D. van Oosten, P. van der Straten, H. T. C. Stoof
We discuss the superfluid to Mott insulator transition of an atomic Bose gas in an optical lattice with high filling factors. We show that also in this multi-band situation, the lo…
Quantum phases in an optical lattice
D. van Oosten, P. van der Straten, H. T. C. Stoof
We present the zero-temperature phase diagram of bosonic atoms in an optical lattice, using two different mean-field approaches. The phase diagram consists of various insulating ph…
