Effective many-particle systems in artificial structures have become an important testbed for the investigation of quantum many-particle and condensed matter physics.
Very recently it has been shown, that arrays of coupled micro-cavities can host effective Bose-Hubbard and spin models. As a new feature, this approach offers the possibility to control and address individual lattice sites. Besides being a prerequisite for quantum information applications, this possibility opens the door to the study of many-particle systems which are inhomogeneous or out of equilibrium.
Here we discuss one such possibility, an interface between a Mott insulator and a superfluid region.
