Radial spectra and dynamical signatures of excited boson stars
Chen-Hao Hao, Wen-Di Guo, Qin Tan +1
We compute the lowest radial mode of spherically symmetric boson stars along equilibrium branches with a fixed number of radial nodes, considering both mini boson stars and quartic…
Charged Regular Black Holes From Quasi-topological Gravities in
Chen-Hao Hao, Jiliang Jing, Jieci Wang
The investigation of gravity in higher-dimensional spacetime has transitioned from a mathematical curiosity to a fundamental framework in theoretical physics, catalyzed by the dime…
Scrambling-Enhanced Quantum Battery Charging in Black Hole Analogues
Zhilong Liu, Ying Li, Zehua Tian +1
Black holes constitute nature's fastest quantum information scramblers, a phenomenon captured by gravitational analogue systems such as position-dependent XY spin chains. In these…
Harvesting entanglement from the Lorentz-violating quantum field vacuum in a dipolar Bose-Einstein condensate
Zehua Tian, Weiping Yao, Xiaobao Liu +3
We theoretically propose an experimentally viable scheme to explore the transfer of nonclassical correlations from a dipolar Bose-Einstein condensate (BEC) to a pair of impurities…
Axion boson stars with wormhole topology
Chen-Hao Hao, Yong-Qiang Wang, Jieci Wang
We investigate a novel gravitational configuration formed by a massless real phantom field and an axion scalar field, minimally coupled to gravity. This system describes an Ellis-t…
Open quantum battery in three-dimensional rotating black hole spacetime
Xiaofang Liu, Zehua Tian, Jieci Wang
We investigate the charging performance of a quantum battery coupled to a scalar field in the background of a three-dimensional rotating black hole. We show that for Dirichlet boun…
