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…
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…
Quantum heat valve and entanglement in superconducting resonators
Yu-qiang Liu, Yi-jia Yang, Ting-ting Ma +1
Quantum superconducting circuit with flexible coupler has been a powerful platform for designing quantum thermal machines. In this letter, we employ the tunable coupling of two sup…
