Nonlinear Conductivity of a Holographic Superconductor Under Constant Electric Field
Hua-Bi Zeng, Yu Tian, Zheyong Fan +1
The dynamics of a two-dimensional superconductor under a constant electric field is studied by using the gauge/gravity correspondence. The pair breaking current induced by …
Note on the butterfly effect in holographic superconductor models
Yi Ling, Peng Liu, Jian-Pin Wu
In this note we remark that the butterfly effect can be used to diagnose the phase transition of superconductivity in a holographic framework. Specifically, we compute the butterfl…
Holographic Butterfly Effect at Quantum Critical Points
Yi Ling, Peng Liu, Jian-Pin Wu
When the Lyapunov exponent in a quantum chaotic system saturates the bound , it is proposed that this system has a holographic dual described by a gravit…
Holographic Metal-Insulator Transition in Higher Derivative Gravity
Yi Ling, Peng Liu, Jian-Pin Wu +1
We introduce a Weyl term into the Einstein-Maxwell-Axion theory in four dimensional spacetime. Up to the first order of the Weyl coupling parameter , we construct charged black…
Nonlinear Transport in a Two Dimensional Holographic Superconductor
Hua Bi Zeng, Yu Tian, Zhe Yong Fan +1
The problem of nonlinear transport in a two dimensional superconductor with an applied oscillating electric field is solved by the holographic method. The complex conductivity can…
Characterization of Quantum Phase Transition using Holographic Entanglement Entropy
Yi Ling, Peng Liu, Jian-Pin Wu
The entanglement exhibits extremal or singular behavior near quantum critical points (QCPs) in many condensed matter models. These intriguing phenomena, however, still call for a w…
