The realization of Bose Einstein condensates (BEC) and quantum degenerate Fermi gases
with cold atoms has been a highlight of quantum physics during the past decade. Cold …

This paper reviews the recent theoretical and experimental advances in the study of ultra-
cold gases made of bosonic particles interacting via the long-range, anisotropic dipole …

In quantum mechanical many-body systems, long-range and anisotropic interactions
promote rich spatial structure and can lead to quantum frustration, giving rise to a wealth of …

Insights into complex phenomena in quantum matter can be gained from simulation
experiments with ultracold atoms, especially in cases where theoretical characterization is …

Using cold atoms to simulate strongly interacting quantum systems is an exciting frontier of
physics. However, because atoms are nominally neutral point particles, this limits the types …

NATURE abounds with phase transitions. The boiling and freezing of water are everyday
examples of phase transitions, as are more exotic processes such as superconductivity and …

Recent experimental progress in trapping and cooling of molecular gases boosts interest in
the interdisciplinary field of quantum gases with dominant dipole–dipole interactions. An …

Josephson-junction arrays are ideal model systems to study a variety of phenomena such as
phase transitions, frustration effects, vortex dynamics and chaos. In this review, we focus on …

The ground state of dipolar bosons placed in an optical lattice is analyzed. We show that the
modification of experimentally accessible parameters can lead to the realization and control …

We study the one-dimensional Bose-Hubbard model using the density-matrix
renormalization group. For the cases of on-site interactions and additional nearest-neighbor …
