Quenched p-wave topological superfluid

This event is part of the Condensed Matter Theory Seminar Series.

Abstract:

A few years ago there were several attempts to create two dimensional topological fermionic superfluid with cold atomic gases using p-wave Feshbach resonance. These attempts did not succeed as it was found that the p-wave superfluid's lifetime was too short for it to equilibrate before decaying. I will describe our work studying the out of equilibrium evolution of a p-wave superfluid which is suddenly quenched close to resonance, before the instability kicks in. We find that the superfluid reaches a steady out of equilibrium state, which retains some of the topological characteristics of the equilibrium p-wave superfluid.
