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…
Distinct Signatures of Dynamical and Spectral Criticality in Quenched Quantum Batteries
Zheng Liu, Wen-Hui Nie, Yi-jia Yang +2
Criticality is widely used to enhance energy storage in quantum batteries. Two criticalities are compared here, one spectral and one dynamical. We ask two questions. Where does the…
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…
