Traveling Dark Solitons in Superfluid Fermi Gases
Traveling Dark Solitons Superfluid Fermi Gases
2010/11/25
Families of dark solitons exist in superfluid Fermi gases. The energy-velocity dispersion and
number of depleted particles completely determines the dynamics of dark solitons on a slowly-
varying ba...

dynamics of dark solitons trapped superfluid Fermi gas

We study soliton oscillations in a trapped superfluid Fermi gas across the Bose-Einstein conden-sate to Bardeen-Cooper-Schrieffer (BEC-BCS) crossover. We derive an exact equation relating the phase ju...

Motion of dark solitons trapped Bose-Einstein condensates

We use a multiple time scale boundary layer theory to derive the equation of motion for a
dark (or ‘grey’) soliton propagating through an effectively one-dimensional cloud of Bose-Einstein condensate...
