Raman-assisted hopping can allow for the creation of density-dependent synthetic magnetism for ultracold neutral gases in optical lattices. In 1D the density-dependent Peierls phases can be mapped the anyon Hubbard model which exhibits a rich groundstate physics including unconventional two-component superfluid phases and statistically driven phase transitions [1]. In 2D square lattices we observe a non-trivial interplay between density modulations and effective magnetic fluxes as well as intriguing dynamical properties [2].
