Holograhic two-currents model with coupling and its conductivites
Dan Zhang, Zhenhua Zhou, Guoyang Fu +1
We implement a holographic gravity model of two gauge fields with a coupling between them, which is dual to a two-currents model. An analytical black brane solution is obtained. In…
Doped holographic fermionic system
Wenjun Huang, Guoyang Fu, Dan Zhang +2
We construct a two-current model. It includes two gauge fields, which introduce the doping effect, and a neutral scalar field. And then we numerically construct an AdS black brane…
Holography of electrically and magnetically charged black branes
Zhenhua Zhou, Jian-Pin Wu, Yi Ling
We construct a new class of black brane solutions in Einstein-Maxwell-dilaton (EMD) theory, which is characterized by two parameters . Based on the obtained solutions, we make…
Particle motion and chaos
Zhenhua Zhou, Jian-Pin Wu
In this note, we consider particle falling in the black hole with an additional potential. Following the proposal by Susskind \cite{Susskind:2018tei}, we study the growth rate of t…
Holographic transports from Born-Infeld electrodynamics with momentum dissipation
Xiao-Mei Kuang, Jian-Pin Wu, Zhenhua Zhou
We construct the Einstein-axions AdS black hole from Born-Infeld electrodynamics. Various DC transport coefficients of the dual boundary theory are computed. The DC electric conduc…
