Cold atomic gases have become a paradigmatic system for exploring fundamental physics,
which at the same time allows for applications in quantum technologies. The accelerating …

We produce Bose-Einstein condensates of two different species, Rb 87 and K 41, in an
optical dipole trap in proximity of interspecies Feshbach resonances. We discover and …

In this review, we provide an introduction to and an overview of some more recent advances
in real-time dynamics of quantum impurity models and their realizations in quantum devices …

We report results of quantum Monte Carlo simulations of the Bose-Hubbard model in three
dimensions. Critical parameters for the superfluid-to-Mott-insulator transition are determined …

We consider bosonic dipolar molecules in an optical lattice prepared in a mixture of different
rotational states. The 1/r 3 interaction between molecules for this system is produced by …

We produce a heteronuclear quantum degenerate mixture of two bosonic species, Rb 87
and K 41, in a three-dimensional optical lattice. On raising the lattice barriers, we observe …

We report the observation of many-body interaction effects for a homonuclear bosonic
mixture in a three-dimensional optical lattice with variable state dependence along one axis …

We introduce a generic bosonic model exemplifying that (spin) Meissner currents can persist
in insulating phases of matter. We consider two species of interacting bosons on a lattice …

We investigate spin-order of ultracold bosons in an optical lattice by means of dynamical
mean-field theory. A rich phase diagram with anisotropic magnetic order is found, both for …

We formulate a bosonic dynamical mean-field theory (B-DMFT) which provides a
comprehensive, thermodynamically consistent framework for the theoretical investigation of …
