摘要: We demonstrate dynamic stabilization of a strongly interacting quantum spin system realized in spin-1 atomic Bose-Einstein condensate. The spinor condensate is initialized to an unstable fixed point the spin-nematic phase space, where subsequent free evolution gives rise squeezing and mixing. To stabilize system, periodic microwave pulses are applied that rotate many-body fluctuations limit their growth. stability diagram for range pulse periods shifts dynamics measured compares well with analysis.
