空间各向异性背景下的全息超导体模型

A holographic superconductor model in a spatially anisotropic background

Jun-ichirou Koga, Kengo Maeda, Kentaro Tomoda

摘要:

本文研究了带电标量场下的Einstein-Maxwell-Einstein理论中超导体的各向异性模型。发现随着各向异性变大,临界温度降低。然后我们估计了超导体的能隙,发现能隙与临界温度的比值随各向异性的增加而增加,比各向同性情况下的要大。我们还发现,peudogap出现由于各向异性。

英文摘要:

We investigate an anisotropic model of superconductors in the Einstein-Maxwell-dilaton theory with a charged scalar field. It is found that the critical temperature decreases as the anisotropy becomes large. We then estimate the energy gap of the superconductor, and find that the ratio of the energy gap to the critical temperature increases as the anisotropy increases and so it is larger than that in the isotropic case. We also find that peudogap appears due to the anisotropy.
