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…

Nonlinear dynamics in an artificial feedback spin maser
Mingjun Feng, Lan Wu, Guobin Liu
Spin masers with optical detection and artificial feedback are widely used in fundamental and practical applications. However, a full picture of the maser dynamics is still absent.…
