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…

Optimized adiabatic-impulse protocol preserving Kibble-Zurek scaling with attenuated anti-Kibble-Zurek behavior
Han-Chuan Kou, Zhi-Han Zhang, Xin-Hui Wu +3
We propose an optimized adiabatic-impulse (OAI) protocol that substantially reduces the evolution time for crossing a quantum phase transition while preserving Kibble-Zurek (KZ) sc…

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…
