Effects of multi-color intensity modulations on a 1D optical lattice — •Lorenzo Cardarelli, Sebastian Greschner, and Luis Santos — Institut für Theoretische Physik, Leibniz Universität Hannover, Appelstr. 2, DE-30167 Hannover, Germany

We study an effective model of a one-dimensional optical lattice loaded with bosonic particles of different spin components, in the presence of a multi-color modulation of the lattice intensity. The modulation opens interesting possibilities of control on the properties of the system, including effective controllable interactions without the need of Feshbach resonances and an effective two-body hard-core constraint. Furthermore, considering a ladder-like lattice in synthetic dimensions, modulation results in a hopping along the real direction (both in amplitude and in phase) that paves the way to the observation of density-dependent synthetic magnetism, along with the generation of inter-site interactions along the real direction without the need of dipolar interactions.
