Chirality, nonreciprocity, and quantum correlations are at the center of a wide range of intriguing effects and applications across natural sciences and emerging quantum technologi…
Continuous field tracking with machine learning and steady state spin squeezing
Junlei Duan, Zhiwei Hu, Xingda Lu +4
Entanglement plays a crucial role in proposals for quantum metrology, yet demonstrating quantum enhancement in sensing with sustained spin entanglement remains a challenging endeav…
Topological atomic spinwave lattices by dissipative couplings
Dongdong Hao, Lin Wang, Xingda Lu +4
Recent experimental advance in creating dissipative couplings provides a new route for engineering exotic lattice systems and exploring topological dissipation. Using the spatial l…
Non-reciprocity and quantum correlations of light transport in hot atoms via reservoir engineering
Xingda Lu, Wanxia Cao, Wei Yi +2
The breaking of reciprocity is a topic of great interest in fundamental physics and optical information processing applications. We demonstrate non-reciprocal light transport in a…
Quantum correlations near the exceptional point
Wanxia Cao, Xingda Lu, Xin Meng +3
Recent advances in non-Hermitian physical systems have led to numerous novel optical phenomena and applications. However, most realizations are limited to classical systems and qua…
Measurements with prediction and retrodiction on the collective spin of 10^{11} atoms beat the standard quantum limit
Han Bao, Junlei Duan, Xingda Lu +10
Quantum probes using uncorrelated particles give a limit on the measurement sensitivity referred to as the standard quantum limit (SQL). The SQL, however, can be overcome by ex…
Neutron Scattering Measurements of Spatially Anisotropic Magnetic Exchange Interactions in Semiconducting K0.85Fe1.54Se2 (TN=280 K)
Jun Zhao, Yao Shen, R. J. Birgeneau +7
We use neutron scattering to study the spin excitations associated with the stripe antiferromagnetic (AFM) order in semiconducting KFeSe (= K). We s…
