DESCRIPTION:A spinor Bose-Einstein condensate (BEC) is highly controllable especially when combining with optical lattices. Lattice-confined spinor BEC is an ideal candidate for studying many non-equilibrium quantum dynamics since it can be easily prepared far from equilibrium. I will present the results of our experimental studies on non-equilibrium quantum spin dynamics in our spinor BEC (23Na) confined by 3D cubic optical lattices. I will first introduce the ground state properties of the system including the superfluid to Mott-insulator phase transitions\, which can be either first-order or second-order. I will then focus on two experiments using quantum quench to drive the system out of equilibrium. Based on the observed spin dynamics we not only find the number distribution in our system\, but also measure the spin-dependent interaction of the atom. The system also serves as a quantum simulator to study the complex many-body dynamics.
