论文摘要

我们提供了一种新颖的方法学方法,用于估计高临界温度超导金属散装样品的量子真空电磁能密度的变化,当它从超导到正常相的温度转变时。强调并比较了两个阶段中Casimir能量的各种贡献。虽然真空模式的TM极化允许对超导转变进行宏观描述,但在微观模型中引入了由超导相关引起的TE真空模式的变化,该模型没有明确考虑材料的各向异性结构。

We provide a novel methodological approach to the estimate of the change of the Quantum Vacuum electromagnetic energy density in a High critical Temperature superconducting metal bulk sample, when it undergoes the transition in temperature, from the superconducting to the normal phase. The various contributions to the Casimir energy in the two phases are highlighted and compared. While the TM polarization of the vacuum mode allows for a macroscopic description of the superconducting transition, the changes in the TE vacuum mode induced by the superconductive correlations are introduced within a microscopic model, which does not explicitly take into account the anisotropic structure of the material.
