Stimulated Emission from Boson Clouds
Yu An, Xian-Hui Ge, Yun-Gui Gong +1
Gravitational-waves from astrophysical sources are characterized by their extreme faintness, which remains a primary obstacle for both current and next generation detectors. While…
Islands in Kerr-Newman Black Holes
Ming-Hui Yu, Xian-Hui Ge
We investigate the information paradox in the four-dimensional Kerr-Newman black hole by employing the recently proposed island paradigm. We first consider the quantum field in the…
Symmetry restoration in a fast scrambling system
Sizheng Cao, Xian-Hui Ge
Entanglement asymmetry -- used here as a direct probe of symmetry restoration -- provides a sharp diagnostic of post-quench dynamics. We test this idea in the complex Sachdev--Ye--…
Replica Wormholes, Modular Entropy, and Capacity of Entanglement in JT Gravity
Ming-Hui Yu, Shu-Yi Lin, Xian-Hui Ge
By employing the replica trick we study the impact of the replica parameter on the modular entropy and the capacity of entanglement in the End of the World (EoW) model and the…
