AI 中文摘要
我们研究了平面大质量狄拉克材料与洛伦兹对称性破缺的Bumblebee-CFJ矢量扇区之间的卡西米尔相互作用。在Lifshitz散射形式中,狄拉克准粒子的标准重整化单圈极化张量被用作非局域表面响应。对于法向取向的洛伦兹破缺背景,表面响应保持宇称偶性。因此,排斥区域并非源于霍尔型电导率,而是源于CFJ引起的TE和TM体模混合,以及狄拉克片层的空间色散响应。此外,我们表明狄拉克质量抑制了相互作用并改变其大距离标度,而CFJ参数驱动吸引与排斥区域之间的转变。
英文摘要
We examine the Casimir interaction between planar massive Dirac materials coupled to a Lorentz-violating Bumblebee-CFJ vector sector. The standard renormalized one-loop polarization tensor of the Dirac quasiparticles is used as the nonlocal surface response in the Lifshitz scattering formalism. For the normally oriented Lorentz-violating background, the surface response remains parity-even. Hence, the repulsive regimes do not originate from a Hall-like conductivity. Instead, they arise from the CFJ-induced mixing of TE and TM bulk modes, combined with the spatially dispersive response of the Dirac sheets. Furthermore, we show that the Dirac mass suppresses the interaction and changes its large-distance scaling, whereas the CFJ parameter drives transitions between attractive and repulsive regimes.
