Quantum dynamics of hard-core bosons in tilted bichromatic optical lattices
Quantum dynamics of hard-core bosons in tilted bichromatic optical lattices
We study the dynamics of strongly repulsive Bose gas in tilted or driven bichromatic optical lattices. Using the Bose-Fermi mapping and exact numerical method, we calculate the reduced single-particle density matrices, and study the dynamics of density profile, momentum distribution and condensate fraction. We show the oscillating and breathing mode …
