Dissipative dynamics of an open quantum battery in the BTZ spacetime
Zehua Tian, Xiaobao Liu, Jieci Wang +1
We consider how charging performances of a quantum battery, modeled as a two-level system, are influenced by the presence of vacuum fluctuations of a quantum field satisfying the D…
Light rings and shadows of static black holes in effective quantum gravity
Wentao Liu, Di Wu, Jieci Wang
Recently, two types of static black hole models that retain general covariance have been proposed within the Hamiltonian constraint approach to effective quantum gravity (EQG). We…
Kerr-MOG-(A)dS black hole and its shadow in scalar-tensor-vector gravity theory
Wentao Liu, Di Wu, Xiongjun Fang +2
The scalar-tensor-vector gravity (STVG) theory has attracted significant interest due to its ability to effectively address the issue of galaxy rotation curves and clusters of gala…
Shadow of slowly rotating Kalb-Ramond black holes
Wentao Liu, Di Wu, Jieci Wang
Real astronomical objects possess spin, yet deriving exact solutions for rotating black holes within gravitational theories is a formidable challenge. To understand the shadow of r…
A model-independent determination of the sound horizon using recent BAO measurements and strong lensing systems
Tonghua Liu, Shuo Cao, Jieci Wang
We propose an improved method to determine the sound horizon in a cosmological model-independent way by using the latest observations of BAO measurements from DES, BOSS/eBOSS, and…
Static neutral black holes in Kalb-Ramond gravity
Wentao Liu, Di Wu, Jieci Wang
The Kalb-Ramond (KR) gravity theory, a modified gravity theory that nonminimally couples a KR field with a nonzero vacuum expectation value for the gravitational field, can spontan…
Model independent calibration for sound horizon combining observations of supernovae and transversal BAO measurements
Tonghua Liu, Xinyi Zhong, Jieci Wang +1
The sound horizon is a key theoretical prediction of the cosmological model that depends on the speed of sound and the rate of expansion in the early universe, before matter and ra…
Optimal quantum strategy for locating Unruh channels
Qianqian Liu, Tonghua Liu, Cuihong Wen +1
From the perspective of quantum information theory, the effect of Unruh radiation on a two-level accelerated detector can be modeled as a quantum channel. In this work, we employ t…
Model-independent way to determine the Hubble constant and the curvature from phase shift of gravitational waves with DECIGO
Tonghua Liu, Shuo Cao, Marek Biesiada +2
In this Letter, we propose a model-independent method to determine the Hubble constant and curvature simultaneously taking advantage of the possibilities of future space-borne grav…
Lorentz violation induces isospectrality breaking in Einstein-Bumblebee gravity theory
Wentao Liu, Xiongjun Fang, Jiliang Jing +1
In this paper, we investigate the quasinormal modes (QNMs) of a Lorentz-violating spacetime, factoring in a cosmological constant, within the framework of Einstein-Bumblebee gravit…
High-order topological pumping on a superconducting quantum processor
Cheng-Lin Deng, Yu Liu, Yu-Ran Zhang +21
High-order topological phases of matter refer to the systems of -dimensional bulk with the topology of -th order, exhibiting -dimensional boundary modes and can be cha…
Multiple measurements on the cosmic curvature using Gaussian process regression without calibration and a cosmological model
Xiaolong Gong, Yifei Xu, Tonghua Liu +4
In this letter, we propose an improved cosmological model-independent method to measure cosmic curvature, combining the recent measurements of transverse and line-of-sight directio…
