Description
A natural description of ultracold gases trapped in optical
lattices is given by the so-called single-band Hubbard
model. We will discuss the additional effects of interaction
to induce intra- as well as inter-band scattering to
neighbouring sites, which shows up as density dependent
correlated tunneling processes. Such processes can
spontaneously give rise to various exotic phases. As
examples, we will present 1) spontaneous creation of
non-Fermi liquid smectic metal phases in dipolar Fermions,
and 2) dynamical generation of exotic lattices in
Fermi-Fermi mixtures.
