At Most One Inner Killing Horizon in Stationary Black Holes
Jing-Peng Ye, Yu-Xuan Li, Run-Qiu Yang +1
Stationary-axisymmetric black holes are the standard theoretical framework for astrophysical black holes, yet their interiors remain largely inaccessible: the absence of a hypersur…
Simulation of the massless Dirac field in 1+1D curved spacetime
Zhilong Liu, Run-Qiu Yang, Heng Fan +1
Simulating the nature of quantum fields in diverse spacetime backgrounds offers valuable insights for the fundamental comprehension of quantum mechanics and general relativity. Her…
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…
Inside Anisotropic Black Hole with Vector Hair
Rong-Gen Cai, Chenghu Ge, Li Li +1
We study the internal structure of anisotropic black holes with charged vector hairs. Taking advantage of the scaling symmetries of the system, some radially conserved charges are…
Constraining the number of horizons with energy conditions
Run-Qiu Yang, Rong-Gen Cai, Li Li
We show that the number of horizons of static black holes can be strongly constrained by energy conditions of matter fields. After a careful clarification on the "interior" of a bl…
Stability analysis on charged black hole with non-linear complex scalar
Zhan-Feng Mai, Run-Qiu Yang
It has been shown recently that the charged black hole can be scalarized if Maxwell field minimally couples with a complex scalar which has nonnegative nonlinear potential. We firs…
Cosmic censorship hypothesis and entropy bound on black holes in a canonical ensemble
Run-Qiu Yang
This paper argues that the weak cosmic censorship hypothesis implies that the Schwarzschild black hole has maximal entropy in all stationary black holes of fixing temperature, or e…
No Inner-Horizon Theorem for Black Holes with Charged Scalar Hairs
Rong-Gen Cai, Li Li, Run-Qiu Yang
We establish a no inner-horizon theorem for black holes with charged scalar hairs. Considering a general gravitational theory with a charged scalar field, we prove that there exist…
Universal bounds on the size of a black hole
Run-Qiu Yang, H. Lu
For static black holes in Einstein gravity, if matter fields satisfy a few general conditions, we conjecture that three characteristic parameters about the spatial size of black ho…
Simulating quantum field theory in curved spacetime with quantum many-body systems
Run-Qiu Yang, Hui Liu, Shining Zhu +2
This paper proposes a new general framework to build a one-to-one correspondence between quantum field theories in static 1+1 dimensional curved spacetime and quantum many-body sys…
Comments on Joint Terms in Gravitational Action
Shan-Ming Ruan, Run-Qiu Yang
This paper compares three different methods about computing joint terms in on-shell action of gravity, which are identifying the joint term by the variational principle in Dirichle…
Strong energy condition and complexity growth bound in holography
Run-Qiu Yang
This paper proves that if eternal neutral black holes satisfy some general conditions and matter fields only appear in the outside of the Killing horizon, the strong energy conditi…

Rong-Gen Cai, Li-Wei Ji, Run-Qiu Yang
The gravitational collapse of a massless scalar field enclosed with a perfectly reflecting wall in a spacetime with a cosmological constant is investigated. The mass scaling fo…
Complexity Growth for AdS Black Holes
Rong-Gen Cai, Shan-Ming Ruan, Shao-Jiang Wang +2
Recently a Complexity-Action (CA) duality conjecture has been proposed, which relates the quantum complexity of a holographic boundary state to the action of a Wheeler-DeWitt (WDW)…
Multi-horizon and Critical Behavior in Gravitational Collapse of Massless Scalar
Zhoujian Cao, Rong-Gen Cai, Run-Qiu Yang

Scaling Laws in Gravitational Collapse
Rong-Gen Cai, Run-Qiu Yang
This paper presents two interesting scaling laws, which relate some critical exponents in the critical behavior of spherically symmetric gravitational collapses. These scaling laws…
