Nonlinear scalarization and thermodynamics in Einstein-Phantom scalar-Gauss-Bonnet theory
Tian-Zhen Dai, Yun Soo Myung, De-Cheng Zou +4
We study nonlinear scalarization of Schwarzschild black-holes for a phantom scalar coupled to the Gauss--Bonnet invariant. Three polynomial couplings satisfying are intr…
A Differential Form Description of Partial Entanglement Entropy: Testing a Killing Vector Construction in Covariant Phase Space
Chuanjia Zhu, Dong-Hui Du, Wen-Cong Gan +1
The bit thread formulation provides a geometric description of holographic entanglement entropy, while partial entanglement entropy (PEE) and PEE threads resolve this structure wit…
Critical Scalarization for a Self-Gravitating Bosonic Condensate
Meng-Yun Lai, Hyat Huang, Wen-Cong Gan +2
We establish a minimal nonrelativistic realization of scalarization in a self-gravitating bosonic condensate coupled to a scalar response field. A local effective-mass shift and no…
Genericness of quantum damping of cosmological shear in modified loop quantum cosmology
Wen-Cong Gan, Leila L. Graef, Rudnei O. Ramos +2
In arXiv:2603.18175, the authors argue, based on numerical studies of particular cases, that the quantum damping of cosmological shear in a modified loop quantum cosmological model…
On Coordinate Singularities Induced by Trapping Horizons
Jinbo Yang, Hongwei Tan, Hyat Huang +1
The trapping (or apparent) horizon serves as a key tool for tracing the complete evolution of black holes. We investigate a class of coordinate singularities induced by such trappi…
A new quantization scheme of black holes in effective loop quantum gravity
Wen-Cong Gan, Anzhong Wang
Loop quantum cosmology has achieved great successes, in which the polymerization plays a crucial role. In particular, the phase-space-variable dependent polymerization turns out to…
Entanglement island and Page curve for one-sided charged black hole

Hongchao Zhang, Wen-Cong Gan, Yungui Gong +1
In this paper, we consider the Böhmer-Vandersloot (BV) model of loop quantum black holes obtained from the improved dynamics approach. We adopt the Saini-Singh gauge, in which it w…
Page curves and Entanglement Islands for the Step-Function Vaidya Model of Evaporating Black Holes
Chang-Zhong Guo, Wen-Cong Gan, Fu-Wen Shu
It was proposed recently that the fine-grained entropy of the Hawking radiation can be expressed by the semiclassical island formula, which reproduces the unitary Page curve. In th…
Nonexistence of quantum black and white hole horizons in an improved dynamic approach
Wen-Cong Gan, Xiao-Mei Kuang, Zhen-Hao Yang +3
In this paper, we study the quantum geometric effects near the locations where classical black hole horizons used to appear in Einstein's classical theory, within the framework of…
A Note on Entanglement Entropy for Primary Fermion Fields in JT Gravity
Chang-Zhong Guo, Wen-Cong Gan, Fu-Wen Shu
In this paper we analyse and discuss 2D Jackiw-Teitelboim (JT) gravity coupled to primary fermion fields in asymptotically anti-de Sitter (AdS) spacetimes. We get a particular solu…
Unitary Constraints on Semiclassical Schwarzschild Black Holes in the Presence of Island
Dong-Hui Du, Wen-Cong Gan, Fu-Wen Shu +1
We reconsider dimensional asymptotically flat eternal Schwarzschild black hole, and focus on the situation where the inner boundary of the radiation region is chosen to be…

Wen-Cong Gan, Geeth Ongole, Emanuele Alesci +3
We systematically study the top-down model of loop quantum black holes (LQBHs), recently derived by Alesci, Bahrami and Pranzetti (ABP). To understand the structure of the model, w…

Great breakthrough in solving black hole information paradox took place when semiclassical island rule for entanglement entropy of Hawking radiation was proposed in recent years. U…

In this paper we systematically study a five-parameters class of spherically symmetric polymer black/white hole solutions, and find that only three independent combinations are phy…
Information loss paradox revisited: farewell firewall?
Wen-Cong Gan, Fu-Wen Shu
Unitary evolution makes pure state on one Cauchy surface evolve to pure state on another Cauchy surface. Outgoing Hawking radiation is only subsystem on the late Cauchy surface. Th…
Characterizing quantum phase transition by teleportation
Meng-He Wu, Yi Ling, Fu-Wen Shu +1
In this paper we provide a novel way to explore the relation between quantum teleportation and quantum phase transition. We construct a quantum channel with a mixed state which is…

A concept of measuring the quantum distance between two different quantum states which is called quantum information metric is presented. The holographic principle (AdS/CFT) sugges…
Holevo Bound of Entropic Uncertainty in Schwarzschild Spacetime
Jin-Long Huang, Wen-Cong Gan, Yunlong Xiao +2
For a pair of incompatible quantum measurements, the total uncertainty can be bounded by a state-independent constant. However, such a bound can be violated if the quantum system i…
