Universal Lichnerowicz Lifting of Near-Horizon Soft Modes
Peng Cheng, Yu-Qi Liu
A remarkable universality appears in the low-temperature quantum thermodynamics of near-extremal black holes, where distinct parent geometries often lead to the same logarithmic te…
On the Universal Cuspy Behavior in Black Hole Shadows
Peng Cheng, Si-Jiang Yang
This work investigates the universality of cusp formation in the shadows of compact objects. The emergence of cusps is accompanied by three interrelated phenomena: a topological ch…
Quantum-corrected black hole thermodynamics from the gravitational path integral
Yu-Qi Liu, Hao-Wei Yu, Peng Cheng
Exploring quantum effects from black hole thermodynamics has always been a pivotal topic. In recent years, the free energy landscape and ensemble-averaged theory based on the Eucli…
Thermodynamics of the Kerr-AdS black hole from an ensemble-averaged theory
Peng Cheng, Jindong Pan, Haichen Xu +1
Exploring the universal structure of the gravitational path integral beyond semi-classical saddles and uncovering a compelling statistical interpretation of black hole thermodynami…
Black hole thermodynamics from an ensemble-averaged theory
Peng Cheng, Yu-Xiao Liu, Shao-Wen Wei
The path integral approach to a quantum theory of gravity is widely regarded as an indispensable strategy. However, determining what additional elements, beyond black hole or AdS s…
