Intrinsic instability of sonic white holes
U. Leonhardt, T. Kiss, P. Ohberg
Artificial black holes, such as sonic holes in Bose-Einstein condensates, may give insights into the role of the physics at the event horizon beyond the Planck scale. We show that…

Theory of elementary excitations in unstable Bose-Einstein condensates
U. Leonhardt, T. Kiss, P. Ohberg
Like classical fluids, quantum gases may suffer from hydrodynamic instabilities. Our paper develops a quantum version of the classical stability analysis in fluids, the Bogoliubov…
