DESCRIPTION:Understanding and classifying out-of-equilibrium dynamics in a
closed quantum many-body system have been outstanding problems in modern p
hysics. In this talk\, I will introduce our recent experimental results on
the universal dynamics far from equilibrium. In the first talk\, a spin-1
Bose-Einstein condensate is adopted to study universal coarsening dynamic
s\, where we quench a polar phase to ferromagnetic phases by microwave dre
ssing. Right after the quench\, we observe the emission of spin 1/-1 pairs
due to dynamical instability\, forming microdomains\, which are coarse to
form a larger domain as time evolves. We find distinctive scaling behavio
r depends on the symmetry of the Hamiltonian and associated dynamics of to
pological defects. In the second part\, I will present the observation of
Family-Visek scaling in 1D XX Heisenberg chains\, where we implement quant
um gas microscopy for single atom detection and manipulate initial states.
Investigating post-quench dynamics of a charge density wave state at diff
erent chain lengths L=8-16\, we measure ballistic dynamical scaling expone
nt. Moreover\, we observe the ballistic transport is changed to diffusive
under random kick during the dynamics.
