Phase transitions in scalarized topological AdS black holes
Zi-Qiang Zhao, Zhang-Yu Nie, Shao-Wen Wei +2
We investigate the behavior of black hole scalarization induced by a charged scalar field in the extended phase space of the asymptotic AdS spacetime with three distinct horizon to…
Identifying lensed gravitational waves with physics-informed posterior learning
Tian-Yang Sun, Xiao Guo, Jing-Fei Zhang +1
Gravitational lensing of gravitational waves can probe compact lenses, dark matter substructure, and cosmological distances, but identifying lensed events is difficult when unrelat…
Universal geometric framework for black hole phase transitions: from multivaluedness to classification
Shi-Hao Zhang, Zi-Yuan Li, Jing-Fei Zhang +1
Recent studies have revealed synchronized multivalued behavior in thermodynamic, dynamical, and geometric quantities during the black hole first-order phase transition, which enabl…
Model-independent H0 from GWTC-4 standard sirens and TDCOSMO 2025 strong lensing time delays
En-Yu Xiong, Ji-Yu Song, Jing-Fei Zhang +1
The significant discrepancy between early- and late-Universe measurements of the Hubble constant, known as the Hubble tension, remains one of the most pressing open questions in co…
Phase separation seeded by Z2 and U(1) topological defects from holography
Zi-Qiang Zhao, Zhang-Yu Nie, Jing-Fei Zhang +1
We study the interaction between spontaneous symmetry breaking and phase separation dynamics in holography. Using a double-quench protocol, the system first rapidly crosses the cri…
Interior structure of black holes with nonlinear terms
Zi-Qiang Zhao, Zhang-Yu Nie, Xing-Kun Zhang +3
We investigate the oscillation of the Kasner exponent near critical point of the hairy black holes dual to holographic superfluid and reveal a clear inverse periodicity $f(T_…
