Doubly-modulated optical lattices

Simon Zhao
Imperial College, London

Optical lattices systems, driven by periodical laser beams or magnetic fields, provide exceptional platforms for quantum simulation of non-trivial many-body systems. In our doubly modulated model, by applying Floquet theory, we are able to create a dominant nearest neighbor interaction in the first order effective Hamiltonian and suppress other tunneling events by choosing suitable driving forces. As a consequence, it will be possible to observe density wave phase in our driven system.
