Query: Quench Dynamics in a Trapped Bose-Einstein Condensate with Spin-Orbit
  Coupling   We consider the phase transition dynamics of a trapped Bose-Einstein
condensate subject to Raman-type spin-orbit coupling (SOC). By tuning the
coupling strength the condensate is taken through a second order phase
transition into an immiscible phase. We observe the domain wall defects
produced by a finite speed quench is described by the Kibble-Zurek mechanism
(KZM), and quantify a power law behavior for the scaling of domain number and
formation time with the quench speed.
