随机带电介质间涨落诱导的相互作用

Fluctuation-Induced Interaction between Randomly Charged Dielectrics

Ali Naji, David S. Dean, Jalal Sarabadani, Ron R. Horgan, Rudolf Podgornik

摘要:

单极电荷无序效应的上下文中的波动引起的中性介质板之间的相互作用进行了研究。它示出,淬火体电荷无序引起的净相互作用力衰减的倒数之间的距离,从而可能完全掩盖了标准的Casimir-范德华力在大的分离添加剂的贡献。相比之下,退火(体或表面)电荷无序导致净相互作用力,其大距离行为与完美导体之间的普遍卡西米尔力相一致,其尺度为立方距离的倒数,并且介电性质仅在子引导校正中进入。

英文摘要:

Monopolar charge disorder effects are studied in the context of fluctuation-induced interactions between neutral dielectric slabs. It is shown that quenched bulk charge disorder gives rise to an additive contribution to the net interaction force which decays as the inverse distance between the slabs and may thus completely mask the standard Casimir--van der Waals force at large separations. By contrast, annealed (bulk or surface) charge disorder leads to a net interaction force whose large-distance behavior coincides with the universal Casimir force between perfect conductors, which scales as inverse cubic distance, and the dielectric properties enter only in subleading corrections.
