HamleyCurrent study in quantum dynamical evolution of complex systems investigates quantum systems characterized by fluctuations and quantum correlations.  Spin-1 condensates are predicted to generate non-classical states with quantum correlations, specifically squeezed states in the early low depletion limit and highly non-Gaussian distributions in the long term beyond the low depletion limit.  These states are created due to the quantum fluctuations about an unstable equilibrium in the spin-nematic subspaces to which the system is initialized.  In this talk I will discuss the underlying theory along with our measurements of spin-nematic squeezing [1], the later non-Gaussian distributions [2], and our efforts to stabilize the initial unstable equilibrium by periodically perturbing the dynamics.1.  C.D.
