Singular transport in non-equilibrium strongly internal-coupled 1D tilted field spin-1/2 chain
Yi-jia Yang, Yu-qiang Liu, Zheng Liu +1
Non-equilibrium spin-chain systems have been attracting increasing interest in energy transport. This work studies a one-dimensional non-equilibrium Ising chain immersed in a tilte…
Weak force sensing based on optical parametric amplification in a cavity optomechanical system coupled in series with two oscillators
Zheng Liu, Yu-qiang Liu, Yi-jia Yang +1
In the realm weak force sensing, an important issue is to suppress fundamental noise (quantum noise and thermal noise), as they limit the accuracy of force measurement. In this pap…
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…
Enhancing Weak magnetic field sensing of cavity-magnon system with dual frequency modulation
Zheng Liu, Yu-qiang Liu, Zi-yi Mai +3
The crucial limitation of improving the sensitivity of the detection of weak magnetic fields is the unavoidable measurement noise. In this paper, we propose a scheme to achieve pre…
Quantum heat valve and diode of strongly coupled defects in amorphous material
Yu-qiang Liu, Yi-Jia Yang, Ting-ting Ma +2
The mechanical strain can control the frequency of two-level atoms in amorphous material. In this work, we would like to employ two coupled two-level atoms to manipulate the magnit…
Magnetically controlled quantum thermal devices via three nearest-neighbor coupled spin-1/2 systems
Yi-jia Yang, Yu-qiang Liu, Zheng Liu +1
A quantum thermal device based on three nearest-neighbor coupled spin-1/2 systems controlled by the magnetic field is proposed. We systematically study the steady-state thermal beh…
