Beyond effective Hamiltonians: micromotion of Bose Einstein condensates in periodically driven optical lattices

We investigate a Bose Einstein condensate held in a 1D optical lattice whose phase undergoes a fast oscillation using a statistical analysis. The averaged potential experienced by the atoms boils down to a periodic potential having the same spatial period but with a renormalized depth. However, the...
