The study of open quantum systems–microscopic systems exhibiting quantum coherence
that are coupled to their environment–has become increasingly important in the past years …

Originally, the Hubbard model was derived for describing the behavior of strongly correlated
electrons in solids. However, for over a decade now, variations of it have also routinely been …

Recent theoretical and experimental progress on studying one-dimensional systems of
bosonic, fermionic, and Bose–Fermi mixtures of a few ultracold atoms confined in traps is …

We present a simple, experimentally realizable method to make coherent three-body
interactions dominate the physics of an ultracold lattice gas. Our scheme employs either …

We investigate geometric resonances in Bose–Einstein condensates by solving the
underlying time-dependent Gross–Pitaevskii equation for systems with two-and three-body …

Traditional anyons in two dimensions have generalized exchange statistics governed by the
braid group. By analyzing the topology of configuration space, we discover that an alternate …

In this Brief Report the extended Bose-Hubbard model with local two-and three-body
interactions is studied by the exact diagonalization approach. The shapes of the first two …

A ground state path integral quantum Monte Carlo algorithm is introduced that allows for the
study of entanglement in lattice bosons at zero temperature. The Rényi entanglement …

When describing the low-energy physics of bosons in a double-well potential with a high
barrier between the wells and sufficiently weak atom-atom interactions, one can, to a good …

We determined perturbatively the low-energy universal thermodynamics of dilute one-
dimensional bosons with the three-body repulsive forces. The final results are presented for …
