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…
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…

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…

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…

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…

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…
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…
Gravity dualities of quantum distances

By choosing modular ground state as the reference state, this paper finds that three most frequently-used distances and a quantum quasi-distance, i.e. the trace distance, Fubini-St…
What kind of "complexity" is dual to holographic complexity?

Run-Qiu Yang, Yu-Sen An, Chao Niu +2
We make comments on some shortcomings of the non-unitary-invariant and non-bi-invariant complexity in quantum mechanics/field theory and argue that the unitary-invariant and bi-inv…
