This review is devoted to the problem of thermalization in a small isolated conglomerate of
interacting constituents. A variety of physically important systems of intensive current interest …

Optical lattices have emerged as ideal simulators for Hubbard models of strongly correlated
materials, such as the high-temperature superconducting cuprates. In optical lattice …

Quantum gases in optical lattices offer an opportunity to experimentally realize and explore
condensed matter models in a clean, tunable system. We used single atom–single lattice …

Understanding exotic forms of magnetism in quantum mechanical systems is a central goal
of modern condensed matter physics, with implications for systems ranging from high …

Strongly correlated materials are expected to feature unconventional transport properties,
such that charge, spin, and heat conduction are potentially independent probes of the …

The dynamics of two penetrating superfluids exhibit an intriguing variety of nonlinear effects.
Using two distinguishable components of a Bose-Einstein condensate, we investigate the …

This is a review of recent developments in Monte Carlo methods in the field of ultracold
gases. For bosonic atoms in an optical lattice we discuss path-integral Monte Carlo …

We analyze in detail the heating of bosonic atoms in an optical lattice due to incoherent
scattering of light from the lasers forming the lattice. Because atoms scattered into higher …

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 …
