非最小导数耦合理论中的全息超导体模型

Holographic superconductor models in the non-minimal derivative coupling theory

Songbai Chen, Qiyuan Pan, Jiliang Jing

摘要:

本文利用Stückelberg机制研究了一类广义的全息超导体模型,在该模型中,带电标量场与爱因斯坦张量动力学耦合.研究了耦合参数对临界温度、相变级数和二级相变点附近的临界指数的影响。此外,我们使用探针近似计算导电性,并检查不同耦合参数的比率$ω_g/T_c$。

英文摘要:

We study a general class of holographic superconductor models via the Stückelberg mechanism in the non-minimal derivative coupling theory in which the charged scalar field is kinetically coupling to Einstein's tensor. We explore the effects of the coupling parameter on the critical temperature, the order of phase transitions and the critical exponents near the second-order phase transition point. Moreover, we compute the electric conductive using the probe approximation and check the ratios $ω_g/T_c$ for the different coupling parameters.
