Stochastic Mean-field Theory for Conditional Spin Squeezing by Homodyne Probing of Atom-Cavity Photon Dressed States
ZhiQing Zhang, HaiZhong Guo, Lingrui Wang +4
Projective measurements of collective observables can be employed to herald the preparation of entangled states of quantum systems, and the resulting conditional dynamics is usuall…

Superradiant Echoes Induced by Multiple Re-phasing of NV Spin Sub-ensembles Grating at Room Temperature
Qilong Wu, Yuan Zhang, Huihui Yu +2
In this Letter, we propose that superradiant echoes can be achieved at room temperature by applying a laser illumination and a microwave Hahn echo sequence to a diamond with a high…

Complementary Collective Spin Descriptions of Superradiant Ramsey Spectroscopy
Ke-Xin Gao, Yuan Zhang, Shi-Lei Su +3
A recent experiment demonstrated delayed superradiance from strontium-88 atoms, which are coupled to a longitudinal mode of a cavity while being excited by laser pulses propagating…
