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…
Non-Exponential Relaxation in the Rotating Frame of a Driven Nanomechanical Mode
Hyunjin Choi, Oriel Shoshani, Ryundon Kim +6
We present direct observation of the ring-down dynamics in the rotating frame of a resonantly driven single-mode nonlinear nanomechanical resonator. An additional close to resonanc…
Intrinsic Phononic Dressed States in a Nanomechanical System
M. Yuksel, M. P. Maksymowych, O. A. Hitchcock +5
Nanoelectromechanical systems (NEMS) provide a platform for probing the quantum nature of mechanical motion in mesoscopic systems. This nature manifests most profoundly when the de…
