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…
