Active Optical Frequency Measurements with Superradiance Prolonged by a Modulated Magnetic Field
Huihui Yu, Shi-Lei Su, Chongxin Shan +2
Superradiant emission from long-lived excited states of an atomic ensemble confined in an optical cavity constitutes a practical source of light with narrow linewidth. In the pulse…
Exact Numerical Solution of Stochastic Master Equations for Conditional Spin Squeezing
ZhiQing Zhang, Yuan Zhang, HaiZhong Guo +3
Stochastic master equations are often used to describe conditional spin squeezing of atomic ensemble, but are limited so far to the systems with few atoms due to the exponentially…
Theoretical Study on Superradiant Raman Scattering with Rubidium Atoms in An Optical Cavity
Huihui Yu, Yuan Zhang, Gang Chen +1
Superradiant Raman scattering of Rubidium atoms has been explored in the experiment [Nature 484, 78 (2012)] to prove the concept of the superradiant laser, which attracts significa…
Superradiant Masing with Solid-state Spins at Room Temperature
Qilong Wu, Yuan Zhang, Hao Wu +5
Steady-state superradiance and superradiant lasing attract significant attentions in the field of optical lattice clocks, but have not been achieved so far due to the technical cha…
