Nonlinear dynamics in an artificial feedback spin maser II: dependence on feedback configurations and time crystal effects
Lan Wu, Qingchang Li, Weiyu Wang +2
Artificial feedback spin masers exhibit rich nonlinear dynamics, yet a systematic framework for understanding and controlling their behaviors remains elusive. In this paper, we con…
Ultralow Frequency Magnetic Comb Using Pulse Modulated Spin Maser
Weiyu Wang, Qingchang Li, Erwei Li +4
Frequency combs are widely used in fundamental physics and practical applications at various areas. Here we report the realization of an ultralow frequency magnetic comb using a pu…
Laser power stabilization using conservation law in acoustic optic modulator
Erwei Li, Qianjin Ma, Weiyu Wang +2
Laser power stabilization plays an important role in modern precision instruments based on atom-laser interactions. Here we demonstrate an alternative active control method of lase…
Observation of Time Crystal in a Spin Maser System
Weiyu Wang, Mingjun Feng, Qianjin Ma +3
Pair interaction potentials between atoms in a crystal are in general non-monotonic in distance, with a local minimum whose position gives the lattice constant of the crystal. A te…
