Dynamical strong coupling and parametric amplification of mechanical modes of graphene drums
TLDR
This work engineers a graphene resonator with large frequency tunability at low temperatures, resulting in a large intermodal coupling strength, and demonstrates that the dynamical inter modal coupling is tunable.Abstract:
Tension-induced tunable mode coupling in graphene drums enables coherent energy transfer between mechanical modes to realize strong coupling and amplification.read more
