Charged scalar gravitational collapse in de Sitter spacetime
Cheng-Yong Zhang, Shao-Jun Zhang, De-Cheng Zou +1
We study the charged scalar collapse in de Sitter spacetimes. With the electric charge, there is one more competitor to join the competition of dynamics in the gravitational collap…
Revisiting holographic superconductors with hyperscaling violation
Qiyuan Pan, Shao-Jun Zhang
We investigate the effect of the hyperscaling violation on the holographic superconductors. In the s-wave model, we find that the critical temperature decreases first and then incr…
Holographic superconductor in hyperscaling violation geometry with Maxwell-dilaton coupling
Shao-Jun Zhang, Qiyuan Pan, Elcio Abdalla
We re-investigate the holographic superconductor in hyperscaling violation geometry by considering the coupling between the probed Maxwell field and the background dilaton. We find…
Holographic Schwinger effect in a confining background with Gauss-Bonnet corrections
Shao-Jun Zhang, E. Abdalla
We study the effect of higher-derivative terms on holographic Schwinger effect by introducing the Gauss-Bonnet term in the gravity sector. Anti-de Sitter (AdS) soliton background i…
Holographic Thermalization in Charged Dilaton Anti-de Sitter Spacetime
Shao-Jun Zhang, E. Abdalla
We study holographic thermalization in spacetimes with a chemical potential and a non-trivial dilaton field. Three non-local observables are used to probe the whole process and inv…
Charged Scalar Perturbations around Garfinkle-Horowitz-Strominger Black Holes
Cheng-Yong Zhang, Shao-Jun Zhang, Bin Wang
We examine the stability of the Garfinkle-Horowitz-Strominger (GHS) black hole under charged scalar perturbations. We find that different from the neutral scalar field perturbation…
