Constraints on Kasner Exponents from Holography and Energy Conditions
Zi-Hao Li, Run-Qiu Yang
A central question in bottom-up holography is whether a given bulk effective theory admits a consistent holographic dual. In this work, we explore whether the near-singularity Kasn…
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…
Curvature-Induced Geometric Universality in Non-Hermitian Anderson Transitions
Chen Wang, Run-Qiu Yang, X. R. Wang +1
In Euclidean space, universality classes of Anderson transitions are primarily determined by symmetry and spatial dimensionality. Here, we present evidence for a geometry-controlle…
Linear Growth of Holographic Time-like Entanglement Entropy and Kasner exponents
Zi-Hao Li, Run-Qiu Yang
The holographic time-like entanglement entropy (TEE) extends entanglement to time-like boundary subregions. While its definitive holographic dictionary remains debated, one concret…
Black Hole Interior and Time-like Entanglement Entropy
Zi-Hao Li, Run-Qiu Yang
We investigate the possibility of using holographic time-like entanglement entropy (TEE) to probe the black hole interior. We choose the complex-valued extremal surface mixing spat…
Quantization-scheme-Independent Energy and Its Implications for Holographic Bounds
Ze Li, Hai-Shan Liu, Zi-Qing Xiao +1
In holographic duality, the total energy of the dual field theory is obtained from the holographic renormalization, which depends not only on the bulk geometry but also on the choi…
Application of Solving Inverse Scattering Problem in Holographic Bulk Reconstruction
Bo-Wen Fan, Run-Qiu Yang
We investigate the problem of bulk metric reconstruction in holography by leveraging the inverse scattering framework applied to boundary two-point correlation functions. We genera…
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…
Holographic quantum distances and replica trick
Zi-Qing Xiao, Run-Qiu Yang
This paper gives concrete examples to exhibit how to use the replica trick to calculate the quantum (quasi-)distances holographically. First, we consider the fidelity and relative…
Testing holographic duality in hyperbolic lattices
Jingming Chen, Feiyu Chen, Linyun Yang +16
The celebrated holographic duality posits a correspondence between a quantum gravity in a bulk spacetime and a quantum field theory (QFT) defined on its lower-dimensional boundary.…
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…
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…
Quantum simulation of Hawking radiation and curved spacetime with a superconducting on-chip black hole
Yun-Hao Shi, Run-Qiu Yang, Zhongcheng Xiang +10
Hawking radiation is one of the quantum features of a black hole that can be understood as a quantum tunneling across the event horizon of the black hole, but it is quite difficult…
Superradiant Instability of Extremal Black Holes in STU Supergravity
Zhan-Feng Mai, Run-Qiu Yang, H. Lu
We investigate the superradiant (in)stability of the extremal multi-charge static black holes in the STU supergravity model, which reduce to the RN black hole when all the charges…
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…
Gravity dualities of quantum distances
