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…
Anomalous parametric resonance in a spin-1/2 chain: dynamical effects of nontrivial topology
Mahmoud T. Elewa, M. I. Dykman
Resonant parametric modulation is a major tool of studying magnetic systems. For a spin-1/2 chain in a strong magnetic field, the resulting excitations can be mapped on fermionic 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…
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…
Hidden vibrational bistability revealed by intrinsic fluctuations of a carbon nanotube
P. Belardinelli, W. Yang, A. Bachtold +2
We demonstrate that a quiet state and large-amplitude self-sustained oscillations can co-exist in a carbon nanotube subject to time-independent drive. A feature of the bistability…
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…
