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…
Spin Resonance in Perspective of Floquet Theory and Brillouin-Wigner Perturbation Method
Mingjun Feng, Guobin Liu
We studied the two-level spin resonance in a new perspective. Using the Floquet theory, the periodic interaction Hamiltonians were transfromed into a time-independent interaction.…
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…
