Avoided level crossing spectroscopy with dressed matter waves

open access: yes, 2008
We devise a method for probing resonances of macroscopic matter waves in shaken optical lattices by monitoring their response to slow parameter changes, and show that such resonances can be disabled by particular choices of the driving amplitude.

Detection of Pair-Superfluidity for bosonic mixtures in optical lattices

open access: yes, 2009
We consider a mixture of two bosonic species with tunable interspecies interaction in a periodic potential and discuss the advantages of low filling factors on the detection of the pair-superfluid phase.

Breakdown of adiabaticity when loading ultra-cold atoms in optical lattices

open access: yes, 2009
Realistic simulations of current ultra-cold atoms experiments in optical lattices show that the ramping up of the optical lattice is significantly nonadiabatic, implying that experimentally prepared Mott insulators are not really in the ground state of ...

Dynamics of gap solitons in a dipolar Bose-Einstein condensate on a three-dimensional optical lattice

open access: yes, 2011
We suggest and study the stable disk- and cigar-shaped gap solitons of a dipolar Bose-Einstein condensate of $^{52}$Cr atoms localized in the lowest band gap by three optical-lattice (OL) potentials along orthogonal directions.

Finite-size effects in Anderson localization of one-dimensional Bose-Einstein condensates

open access: yes, 2010
We investigate the disorder-induced localization transition in Bose-Einstein condensates for the Anderson and Aubry-Andre models in the non-interacting limit using exact diagonalization.

Anomalous elasticity in a disordered layered XY model

open access: yes, 2012
We investigate the effects of layered quenched disorder on the behavior of planar magnets, superfluids, and superconductors by performing large-scale Monte-Carlo simulations of a three-dimensional randomly layered XY model.
