本文研究了在AdS黑洞和AdS孤子背景下条纹全息超导体的引力涨落。我们显示的凝聚和临界温度/临界化学势上的不均匀性,在这两个不同的时空的依赖性。通过标量场微扰对正常相位的动力学研究,我们认为对磁化率和电导率可能是揭示非均匀性的唯象指示。
We study the gravity duals of striped holographic superconductors in the AdS black hole and AdS soliton backgrounds. We show the dependences of the condensation and the critical temperature/critical chemical potential on the inhomogeneity in these two different spacetimes. By exploring the dynamics of the normal phase through the scalar field perturbation, we argue that the pair susceptibility and the conductivity can be possible phenomenological indications to disclose the property of inhomogeneity.
