A natural description of ultracold gases trapped in optical lattices
is given by the so-called Hubbard model characterized by the
single-particle tunneling rate, on-site and long-range interaction
strengths. In this presentation we will talk about interaction-induced
extension of such models, namely correlated intra- and inter-orbital
tunneling and renormalized interactions.As concrete examples, we will describe how such terms can give rise to novel phases in ultracold dipolar systems.
Coffee and cookies will be served 15 minutes before the start of the seminar
