Design and geometry dependence of effective Hamiltonians in driven lattices — •Albert Verdeny1,2 and Florian Mintert1,2 — 1Department of Physics, Imperial College London, London SW7 2AZ, United Kingdom — 2Freiburg Institute for Advanced Studies, Albert-Ludwigs-Universität, 79104 Freiburg, Germany
Driven lattices permit to engineer effective Hamiltonians with well-controllable tunneling properties. We discuss the design of such effective Hamiltonians and identify fundamental constraints imposed by the underlying lattice geometry. With the specific example of a hexagonal lattice we show how suitably chosen driving forces overcome limitations of monochromatic driving and permit to realize systems with non-trivial topological properties.
