| Abstract: | We investigate the entanglement dynamics of a generic-spin model with weak external field. We first derive the time-dependent solutions of angular momentum operators with short-time approximation and then numerically calculate the entangled witness. It’s shown that one can dynamically generate quantum entanglement by adjusting coupling strength. |
