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 …

The first book dedicated to this new and powerful computational method begins with a
comprehensive description of MCTDH and its theoretical background. There then follows a …

The evolution of Bose-Einstein condensates is amply described by the time-dependent
Gross-Pitaevskii mean-field theory which assumes all bosons to reside in a single time …

With experimental realization of atomic Bose–Einstein condensation (BEC) and rapid
development of laser cooling and trapping techniques, all optical routes to quantum …

The first-and second-order correlation functions of trapped interacting Bose-Einstein
condensates are investigated numerically on a many-body level from first principles …

We study an ultracold Bose gas in the presence of 1D disorder for repulsive interatomic
interactions varying from zero to the Thomas-Fermi regime. We show that for weak …

We investigate the general structure of orbital exchange physics in Mott-insulating states of p-
orbital systems in optical lattices. Orbital orders occur in both the triangular and kagome …

We investigate few-boson tunneling in a one-dimensional double well, covering the full
crossover from weak interactions to the fermionization limit of strong correlations. Based on …

In this work we develop a complete variational many-body theory for a system of N trapped
bosons interacting via a general two-body potential. The many-body solution of this system …

We present an exact analytical solution of the fundamental system of quasi-one-dimensional
spin-1 bosons with infinite δ repulsion. The eigenfunctions are constructed from the wave …
