A Supersymmetry Approach to Billiards with Randomly Distributed Scatterers II: Correlations
Thomas Guhr, Hans-Juergen Stoeckmann
In a previous contribution (H.J. Stoeckmann, J. Phys. A35, 5165 (2002)), the density of states was calculated for a billiard with randomly distributed delta-like scatterers, doubly…

Phases of a rotating Bose-Einstein condensate with anharmonic confinement
A. D. Jackson, G. M. Kavoulakis, E. Lundh
We examine an effectively repulsive Bose-Einstein condensate of atoms that rotates in a quadratic-plus-quartic potential. With use of a variational method we identify the three pos…
