Dark Solitons in Holographic Superfluids
arXiv:0906.5217 · doi:10.1103/PhysRevD.80.121901
Abstract
We construct dark soliton solutions in a holographic model of a relativistic superfluid. We study the length scales associated with the condensate and the charge density depletion, and find that the two scales differ by a non-trivial function of the chemical potential. By adjusting the chemical potential, we study the variation of the depletion of charge density at the interface.
