Long timescale dynamics in a degenerate F=1 $^{87}$Rb spinor Bose gas

ORAL

Abstract

We report on the long timescale behavior of a quasi two-dimensional spinor gas produced by cooling unmagnetized F=1 $^{87}$Rb spin mixtures. Using in-situ magnetization sensitive imaging, we are able to spatially and temporally resolve the vector magnetization profile of the spinor condensate. We explore the long timescale properties of the ferromagnetic (paramagnetic) spinor condensate at variable quadratic shift. At short evolution times, transverse and longitudinal ferromagnetic domains and domain walls spontaneously form throughout the condensate, while at long evolution times we observe the system evolve towards a homogeneously magnetized condensate, independent of the initially prepared spin mixture.
