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…
