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…

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…

Enhanced Sensing by Geometric Tuning of YIG Spheres: Noise Reduction, Signal Amplification and Directional Magnetic Field Detection
Zheng Liu, Ding-hui Xu, Yi-jia Yang +1
Noise suppression and directional signal enhancement are essential challenges in detecting weak magnetic fields in cavity electrodynamics systems. Traditional schemes struggle to r…
