Multibranched parametric resonance and swallowtail catastrophe in electromechanical oscillators with nonlinear friction
P. Y. Chan, L. Huang, X. Dong +2
Parametric resonance underpins the operation of a wide range of physical systems, from nanomechanical resonators to quantum-information systems and Ising machines. As an archetypal…

Dispersive mode coupling in -doped semiconductor nanomechanical resonators
Ankang Liu, Mahmoud T. Elewa, Mark I. Dykman
Dispersive coupling between vibrational modes with different frequencies is a major nonlinear dynamical effect. We show that in -doped semiconductors such coupling is strongly e…
