| 中文摘要 | Based on algebraic dynamics and the concept of the concurrence of the entanglement, we investigate the evolutive properties oft he two-qubit entanglement that formed by Heisenberg XXX models under a time-depending external field. For this system, the property of the concurrence that is only dependent on the coupling constant J and total values of the external field is proved. Furthermore, we found that the thermal concurrence of the system under a static random external field is a function of the coupling constant J, temperature T, and the magnitude of external field. |
