On holographic time-like entanglement entropy
Ze Li, Zi-Qing Xiao, Run-Qiu Yang
In order to study the pseudo entropy of time-like subregions holographically, the previous smooth space-like extremal surface was recently generalized to mix space-like and time-li…
Using black holes as rechargeable batteries and nuclear reactors
Zhan-Feng Mai, Run-Qiu Yang
This paper proposes physical processes to use a Schwarzschild black hole as a rechargeable battery and nuclear reactor. As a rechargeable battery, it can at most transform 25\% of…
Tightening the Penrose Inequality
H. Khodabakhshi, H. Lu, Run-Qiu Yang
The Penrose inequality estimates the lower bound of the mass of a black hole in terms of the area of its horizon. This bound is relatively loose for extremal or near extremal black…
When null energy condition meets ADM mass
Run-Qiu Yang, Li Li, Rong-Gen Cai
We give a conjecture on the lower bound of the ADM mass by using the null energy condition. The conjecture includes a Penrose-like inequality $3M\geqκ\mathcal{A}/(4π)+\sqrt{\ma…
Upper bounds of holographic entanglement entropy growth rate for thermofield double states
Ze Li, Run-Qiu Yang
We studied the upper bounds of the holographic entanglement entropy growth rate for thermofield double (TFD) states. By comparing the cases of vacuum AdS and charged AdS black hole…
Interior Structure and Complexity Growth Rate of Holographic Superconductor from M-Theory
Yu-Sen An, Li Li, Fu-Guo Yang +1
We study the interior dynamics of a top-down holographic superconductor from M-theory. The condense of the charged scalar hair necessarily removes the inner Cauchy horizon and the…
On Penrose inequality in holography
Zi-Qing Xiao, Run-Qiu Yang
The recent holographic deduction of Penrose inequality only assumes null energy condition while the weak or dominant energy condition is required in usual geometric proof. This pap…
On the applicability of holography in thermodynamic equilibrium
Run-Qiu Yang, Li Li, Rong-Gen Cai
For a strongly coupled system that has a gravity dual description, we show that the standard holographic dictionary yields a nonnegative susceptibility when the system is in thermo…
Extremal Charged Black Holes and Superradiantly Unstable Quasinormal Modes
Zhan-Feng Mai, Run-Qiu Yang, H. Lü
It was recently shown that the extremal charged black holes in STU supergravity suffer from superradiant instability owing to the existence of the unstable (low-frequency) quasibou…
