论文摘要
在Ginzburg-Landau超导过渡的功能框架内，我们分析了临界温度的波动驱动的变化。除了顺序参数波动外，我们还考虑了矢量电位高于真空的波动。我们详细介绍了基于Hartree-Bogoliubov-Popov框架的近似方案，以包括波动场的贡献。就易于访问的实验参数而言，我们给出了$ d = 2 $和$ d = 3 $ d = 3 $的明确结果磁穿透长度和相干性。
Within the Ginzburg-Landau functional framework for the superconducting transition, we analyze the fluctuation-driven shift of the critical temperature. In addition to the order parameter fluctuations, we also take into account the fluctuations of the vector potential above its vacuum. We detail the approximation scheme to include the fluctuating fields contribution, based on the Hartree-Fock-Bogoliubov-Popov framework. We give explicit results for $d=2$ and $d=3$ spatial dimensions, in terms of easily accessible experimental parameters such as the Ginzburg-Levanyuk number $\text{Gi}_{(d)}$, which is related to the width of the critical region where fluctuations cannot be neglected, and the Ginzburg-Landau parameter $κ$, defined as the ratio between the magnetic penetration length and the coherence one.
