We investigate the condition for the condensation of the scalar field over the parameter space, and then focus on the superconductivity over the insulating phase with a hard gap, which is supposed to be Mott-like. It turns out that the formation of the hard gap in the insulating phase benefits the superconductivity.This phenomenon is analogous to the fact that the pseudogap phase can promote the pre-pairing of electrons in high Tccuprates. We expect that this work can shed light on understanding the mechanism of high Tcsuperconductivity from the holographic side.展开更多

This holographic-JinLuo system consists of holographic-points representing channels and collaterals as well as musculature of the traditional JinLuo system, respectively. It uncovers a new dimension of JinLuo, has far-reaching significance in the research on JinLu o.展开更多
