Dark Solitons in Holographic Superfluids

Understand

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.
