In this paper we investigate the model of the anti-de Sitter gravity coupled to a Maxwell field and a free, complex scalar field, and construct a fully back-reacted holographic model of superconductor with excited states. With the fixed charge q, there exist a series of excited states of holographic superconductor with the corresponding critical chemical potentials. The condensates as functions of the temperature for the two operators \({\mathcal {O}}_1\) and \({\mathcal {O}}_2\) of excited states are also studied. For the optical conductivity in the excited states, we find that there exist the additional peaks in the imaginary and real parts of the conductivity. Moreover, the number of peaks corresponding to n-th excited state is equal to n.

具有反向反应的全息超导体的激发态

在本文中,我们研究了与麦克斯韦场和自由复标量场耦合的反德西特引力模型,并构建了具有激发态的超导体的完全反向反应全息模型。对于固定电荷q,存在一系列具有相应临界化学势的全息超导体激发态。还研究了作为激发态的两个算子\({\mathcal {O}}_1\)\({\mathcal {O}}_2\)的温度函数的凝聚物。对于激发态的光导率,我们发现在电导率的虚部和实部存在附加峰。而且,对应于n的峰-th 激发态等于n
