Atomic Regional Superfluids in two-dimensional Moiré Time Crystals
Weijie Liang, Weiping Zhang, Keye Zhang
Moiré physics has transcended spatial dimensions, extending into synthetic domains and enabling novel quantum phenomena. We propose a theoretical model for a two-dimensional (2D) M…
Autonomous Quantum Heat Engine Enabled by Molecular Optomechanics and Hysteresis Switching
Baiqiang Zhu, Pierre Meystre, Weiping Zhang +1
By integrating molecular optomechanics with molecular switches, we propose a scheme for a molecular quantum heat engine that operates autonomously through hysteretic feedback witho…
Enhanced Quantum Metrology with Non-Phase-Covariant Noise
Jia-Xin Peng, Baiqiang Zhu, Weiping Zhang +1
The detrimental impact of noise on sensing performance in quantum metrology has been widely recognized by researchers in the field. However, there are no explicit fundamental laws…
Estimation theory of photon-magnon coupling strength in a driven-dissipative double-cavity-magnon system
Jia-Xin Peng, Baiqiang Zhu, Weiping Zhang +1
Cavity-magnon systems are emerging as a fruitful architecture for the integration of quantum technologies and spintronic technologies, where magnons are coupled to microwave photon…
