Vortex liquids and vortex quantum Hall states in trapped rotating Bose gases
Uwe R. Fischer, Petr O. Fedichev, Alessio Recati
We discuss the feasibility of quantum Hall states of vortices in trapped low-density two-dimensional Bose gases with large particle interactions. For interaction strengths larger t…
Warped space-time for phonons moving in a perfect nonrelativistic fluid
Uwe R. Fischer, Matt Visser
We construct a kinematical analogue of superluminal travel in the ``warped'' space-times curved by gravitation, in the form of ``super-phononic'' travel in the effective space-time…
On the space-time curvature experienced by quasiparticle excitations in the Painleve-Gullstrand effective geometry
Uwe R. Fischer, Matt Visser
We consider quasiparticle propagation in constant-speed-of-sound (iso-tachic) and almost incompressible (iso-pycnal) hydrodynamic flows, using the technical machinery of general re…
Existence of Long-Range Order for Trapped Interacting Bosons
Uwe R. Fischer
We derive an inequality governing ``long range'' order for a localized Bose-condensed state, relating the condensate fraction at a given temperature with effective curvature radius…
