Probing Lorentz-invariance-violation with quantum coherence of Unruh-DeWitt detector
Yihao Wu, Xiaobao Liu, Zehua Tian
Testing Lorentz invariance violation (LIV) is notoriously difficult, as its characteristic energy scale, , in modified dispersion relations typically lies beyond current e…
Stronger Entanglement Dies Faster: Quantum Mpemba Effect in Dissipative Qubits
Zhilong Liu, Zehua Tian, Jieci Wang
In classical thermodynamics, the Mpemba effect refers to the counterintuitive observation that hot water can freeze faster than cold water, manifesting as an anomalous crossing of…
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…
Escape of quantum information across an analogue black hole horizon
Zhilong Liu, Wentao Liu, Zehua Tian +1
The complete evaporation of black holes, as a natural endpoint of Hawking radiation, gives rise to the black hole information paradox, which fundamentally challenges the principles…
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…
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…
