中文摘要：
本文研究了各向异性自旋1/2海森堡链中首尾粒子的纠缠动力学，其中外磁场和最近邻耦合是周期性调制的。在特定的外磁场调制频率和外磁场振幅下，将会出现纠缠共振。在某些特定频率下，最大纠缠可以在相当大的振幅范围内保持最大值。因此，可以通过外界磁场来调控纠缠。
英文摘要：
The entanglement dynamics between two end spins in an anisotropic spin -1/2 Heisenberg chain is investigated when the external magnetic field and the nearest-neighbor coupling are periodically modulated. The entanglement resonance occurs at certain modulation frequency and magnitude of the external magnetic filed. The maximum enta keep the maximum for quite broad range of the external magnetic field. nglement appea the magnitude. rs only at some specific frequencies while it can Thus, the entanglement can be controlled by
