摘要

研究了在静磁场诱导的磁偶极-偶极相互作用和外部激光场诱导产生的偶极-偶极相互作用下光晶格自旋链中磁振子激发的动力学特征. 文中选取了蓝失谐光晶格, 提出了等效温度的概念, 并将系统中磁振子的激发过程与光学振动腔中光子的激发过程进行了类比. 研究表明, 通过选取适当的系统参数, 可以在磁振子系统中重现有限温度下光子的动力学Casimir效应.

In this paper, we study the dynamical characteristics of magnons generated by the static magnetic dipole-dipole interaction and the external-laser induced dipole-dipole interaction in spin chain within an optical lattice. Specially, we choose a blue-detuned optical lattice and define an effective temperature for the system. We make a comparison between the generation process of magnons and that of photons in an optical vibration cavity. The results show that by suitably choosing the system parameters, the dynamical Casimir effect at finite temperature in the magnon system can be reproduced.
