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…

Frequency stabilization of self-sustained oscillations in a sideband-driven electromechanical resonator
B. Zhang, Yingming Yan, X. Dong +2
We present a method to stabilize the frequency of self-sustained vibrations in micro- and nanomechanical resonators. The method refers to a two-mode system with the vibrations at s…

Controlled asymmetric Ising model implemented with parametric micromechanical oscillators
C. Han, M. Wang, B. Zhang +2
Asymmetric Ising model, in which coupled spins affect each other differently, plays an important role in diverse fields, from physics to biology to artificial intelligence. We show…
