Controllable diffusion of cold atoms in a harmonically driven and tilted optical lattice: Decoherence by spontaneous emission Controllable Diffusion of Cold Atoms

The cold atoms on optical lattices provide a paradigmatic model to test some novel quantum phenomena predicted half century back for metallic systems[1,2]. With the advancements in cold atom physics and optical laser technology, it is now possible to precisely control and measure various physical parameters. Cold atoms on optical lattices constitute clean quantum systems as compared to solid st...

Quantum transport of bosonic cold atoms in double-well optical lattices

We numerically investigate, using the time evolving block decimation algorithm, the quantum transport of ultracold bosonic atoms in a double-well optical lattice through slow and periodic modulation of the lattice parameters (intraand inter-well tunneling, chemical potential, etc.). The transport of atoms does not depend on the rate of change of the parameters (as along as the change is slow) a...
