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 …

An overview of the physics of spinor and dipolar Bose–Einstein condensates (BECs) is
given. Mean-field ground states, Bogoliubov spectra, and many-body ground and excited …

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 trap** 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 …

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 …

On June 19th 1999, the European Ministers of Education signed the Bologna Declaration,
with which they agreed that the European university education should be uniformized …

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 present the zero-temperature phase diagram of bosonic atoms in an optical lattice, using
two different mean-field approaches. The phase diagram consists of various insulating …

The zero-temperature phase diagram of the one-dimensional Bose-Hubbard model with
nearest-neighbor interaction is investigated using the density-matrix renormalization group …
