Dissipation-engineered dual-charger quantum batteries
Yi-jia Yang, Yu-qiang Liu, Zheng Liu +3
Suppressing coherent energy backflow while maintaining extractable energy in a stable nonequilibrium state remains a central challenge for quantum energy storage. Here, we introduc…
Dynamical Criticality Behind Energy-Storage Singularities in Quantum Batteries
Zheng Liu, Wen-Hui Nie, Yi-jia Yang +2
Energy-storage singularities in quantum batteries are often associated with equilibrium quantum criticality. Here we show that, in quench-driven many-body batteries, such singulari…
Quantum Magnetometry with Orientation beyond Steady-State Limits in Cavity-Magnon Systems
Zheng Liu, Ding-hui Xu, Yi-jia Yang +2
We propose a transient vector quantum magnetometry protocol based on cavity-magnon systems. By exploiting finite-time dynamics initialized from a reservoir-engineered squeezed stea…
Dissipative Quantum Battery in the Ultrastrong Coupling Regime Between Two Oscillators
Yu-qiang Liu, Yi-jia Yang, Zheng Liu +6
In this work, we propose an open quantum battery that stores and releases energy by employing a two-mode ultrastrongly coupled bosonic system, with one mode (the charger) coupled t…
Quantum thermal diode with additional control by auxiliary atomic states
Qin Zhang, Zi-chen Zhang, Yi-jia Yang +2
A quantum thermal diode, similar to an electronic diode, allows for unidirectional heat transmission. In this paper, we study a quantum thermal diode composed of two two-level atom…
Enhancing optomechanical force sensing utilizing synthetic magnetism
Ding-hui Xu, Zheng Liu, Chang-shui Yu
In precision force sensing of multi-mechanical mode optomechanical systems, coherent interference can decouple certain degenerate vibrational modes from the cavity field, leading t…
