Observation of dipole-dipole interaction in a degenerate quantum gas
J. Stuhler, A. Griesmaier, T. Koch +5
We have investigated the expansion of a Bose-Einstein condensate (BEC) of strongly magnetic chromium atoms. The long-range and anisotropic magnetic dipole-dipole interaction leads…
Emergence of thermodynamic behavior within composite quantum systems
Guenter Mahler, Jochen Gemmer, Mathias Michel
Entanglement within a given device provides a potential resource for quantum information processing. Entanglement between system and environment leads to decoherence (thus suppress…
Capillary-induced interactions between colloids at an interface
Alvaro Dominguez, Martin Oettel, Siegfried Dietrich
Within a general framework we study the effective, deformation-induced interaction between two colloids trapped at a fluid interface. As an application, we consider the interface d…
Lattice Boltzmann simulations of apparent slip in hydrophobic microchannels
Jens Harting, Christian Kunert, Hans J. Herrmann
Various experiments have found a boundary slip in hydrophobic microchannel flows, but a consistent understanding of the results is still lacking. While Molecular Dynamics (MD) simu…
From Pure Schroedingerian to Statistical Dynamics
Jochen Gemmer, Mathias Michel
Many processes in nature seem to be entirely controlled by transition rates and the corresponding statistical dynamics. Some of them are in essence quantum, like the decay of excit…
Magnetocaloric effect in two-dimensional spin-1/2 antiferromagnets
A. Honecker, S. Wessel
The magnetocaloric effect is studied at the transition to saturation in the antiferromagnetic spin-1/2 Heisenberg model on the simplest two-dimensional lattices, namely the square…
