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.…

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…
