Quantum transport of bosonic cold atoms in double-well optical lattices
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 ultra-cold bosonic atoms in a double well optical lattice through slow and periodic modulation of the lattice parameters (intra- and inter-well tunneling, chemical potential, etc.). The transport of atoms does not depend on the rate of …
