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…
Topologically non-trivial field configurations - interplay of vortices and Dirac eigenmodes
Stefan Solbrig, Jochen Gattnar, Christof Gattringer +4
Gluon field configurations with non-trivial topology like instantons, magnetic monopoles and center vortices play a crucial role in QCD and, in particular, for the spontaneous brea…
Smoothness of Wave Functions in Thermal Equilibrium
Roderich Tumulka, Nino Zanghi
We consider the thermal equilibrium distribution at inverse temperature , or canonical ensemble, of the wave function of a quantum system. Since spaces contain more no…
On Superselection Rules in Bohm-Bell Theories
Samuel Colin, Thomas Durt, Roderich Tumulka
The meaning of superselection rules in Bohm-Bell theories (i.e., quantum theories with particle trajectories) is different from that in orthodox quantum theory. More precisely, the…
The Analogue of Bohm-Bell Processes on a Graph
Roderich Tumulka
Bohm-Bell processes, of interest in the foundations of quantum field theory, form a class of Markov processes generalizing in a natural way both Bohm's dynamical system in co…
Spectral analyses of DO white dwarfs and PG1159 stars from the Sloan Digital Sky Survey
S. D. Huegelmeyer, S. Dreizler, K. Werner +3
We present a model atmosphere analysis of ten new DO white dwarfs and five new PG 1159 stars discovered in the Sloan Digital Sky Survey DR1, DR2 and DR3. This is a significant incr…
