Build-up of coherence between initially-independent subsystems: The case of Bose-Einstein condensates
O. E. Alon, A. I. Streltsov, L. S. Cederbaum
When initially-independent subsystems are made to contact, {\it coherence} can develop due to interaction between them. We exemplify and demonstrate this paradigm through several s…
Resonant tunneling of Bose-Einstein condensates in optical lattices
Alessandro Zenesini, Carlo Sias, Hans Lignier +7
In this article, we present theoretical as well as experimental results on resonantly enhanced tunneling of Bose-Einstein condensates in optical lattices both in the linear case an…
The trapped two-dimensional Bose gas: from Bose-Einstein condensation to Berezinskii-Kosterlitz-Thouless physics
Zoran Hadzibabic, Peter Krüger, Marc Cheneau +2
We analyze the results of a recent experiment with bosonic rubidium atoms harmonically confined in a quasi-two-dimensional geometry. In this experiment a well defined critical poin…
Formation and dynamics of many-boson fragmented states in attractive one-dimensional ultra-cold gases
Alexej I. Streltsov, Ofir E. Alon, Lorenz S. Cederbaum
Dynamics of attractive ultra-cold bosonic clouds in one dimension are studied by solving the many-particle time-dependent Schrödinger equation. The initially coherent wave-packet c…
Dark matter-wave solitons in the dimensionality crossover
G. Theocharis, P. G. Kevrekidis, M. K. Oberthaler +1
We consider the statics and dynamics of dark matter-wave solitons in the dimensionality crossover regime from 3D to 1D. There, using the nonpolynomial Schrödinger mean-field model,…
Functional renormalisation group approach to far-from-equilibrium quantum field dynamics
Thomas Gasenzer, Jan M. Pawlowski
Dynamic equations for quantum fields far from equilibrium are derived by use of functional renormalisation group techniques. The obtained equations are non-perturbative and lead su…
