Time Evolution of a Holographic Superfluid

For all of our initial conditions, movies of the time evolution of the superfluid are displayed when following the respective links below. For the random vortex distributions the superfluid's density and a corresponding occupation number spectrum is shown. For the vortex lattice initial conditions, the phase of the superfluid is shown in addition.

We study the approach to the non-thermal fixed point in a reduced configuration space consisting of two characteristic length scales of the system. Follow the link below for a video showing the evolution of the holographic superfluid in this reduced configuration space starting from our various initial conditions.

Further insight into the effective vortex dynamics can be gained by analysing the interaction of a vortex-anti-vortex pair. For a video showing the evolution of such a pair follow the link below. Again, the superfluid's density, the phase, and the corresponding occupation number spectrum is shown.
