We consider strongly interacting systems of effective spins, subject to dissipative spin-flip
processes associated with optical pumping. We predict the existence of novel magnetic …

We review recent experimental and theoretical progress in realizing and simulating many-
body phases of ultracold atoms in optical lattices, which gives access to analog quantum …

We demonstrate a new cooling method in which a time-varying magnetic field gradient is
applied to an ultracold spin mixture. This enables preparation of isolated spin distributions at …

Many-body effects are at the very heart of diverse phenomena found in condensed-matter
physics. One striking example is the Mott-insulator phase, where conductivity is suppressed …

Trapped quantum gases can be cooled to impressively low temperatures,, but it is unclear
whether their entropy is low enough to realize phenomena such as d-wave …

This article reviews some recent developments for new cooling technologies in the fields of
condensed matter physics and cold gases, both from an experimental and theoretical point …

We establish the full ground state phase diagram of the disordered Bose-Hubbard model in
two dimensions at a unity filling factor via quantum Monte Carlo simulations. Similarly to the …
