概 要 | An experimental setup with ultracold Chromium atoms trapped in an optical lattice potential offers a platform for experimentally studying coherent non-equilibrium dynamics of a large quantum many-body spin-model in a controlled environment. We developed a semi-classical technique (the generalized discrete truncated Wigner approximation, GDTWA) that makes it possible to model the many-body evolution of this large three-dimensional and long-range interacting spin-3 model numerically. Here we present this new method and how it can be used to understand the experimentally observed dynamics of spin-state populations in terms of build-up of quantum entanglement and quantum thermalization concepts. |
