有限温度和单轴各向异性对三维拓扑绝缘体Casimir效应的影响

Effect of finite temperature and uniaxial anisotropy on the Casimir effect with three-dimensional topological insulators

Adolfo G. Grushin, Pablo Rodriguez-Lopez, Alberto Cortijo

摘要:

本文研究了三维拓扑绝缘体的Casimir效应,包括温度和单轴各向异性的影响。虽然这些材料的光学性质的精确实验值尚未建立,定性分析仍然是可能的。我们定性地发现,报告的排斥行为和平衡点是系统的强大功能,并有利于低温和平行于光轴的光学响应的增强。讨论了三维拓扑绝缘体的平衡点随温度的变化关系以及与拓扑磁电极化率特性的关系。

英文摘要:

In this work we study the Casimir effect with three-dimensional topological insulators including the effects of temperature and uniaxial anisotropy. Although precise experimental values for the optical properties of these materials are yet to be established, qualitative analysis is still possible. We find qualitatively that the reported repulsive behavior and the equilibrium point are robust features of the system, and are favored by low temperatures and the enhancement of the optical response parallel to the optical axis. The dependence of the equilibrium point with temperature and with the topological magnetoelectric polarizability characteristic of three-dimensional topological insulators is also discussed.
