Transport Optimization in Optical Lattices via Barrier Modulation

We demonstrate that transport characteristics of an arbitrary optical lattice can be greatly-enhanced by modulating the field intensity that generates the lattice structure. We propose, analyze, and derive effective models for two modulation schemes in the strongly interacting limit. For the specific five-site lattices discussed, we numerically predict transport gains ranging from $3\times 10^6$ to roughly $4\times 10^{10}$. After a detailed study of transport optimization in this limit, we discuss the modifications necessary to recover transport for the finite interaction case.
