Frequency Stability of Graphene Nonlinear Parametric Oscillator
Enise Kartal, Oriel Shoshani, Elena Botnaru +3
High-frequency stability is crucial for the performance of graphene resonators in sensing and timekeeping applications. However, the extreme miniaturization and high mechanical com…
Relaminarization of turbulent puffs in pipe flow
Basheer A. Khan, Shai Arogeti, Oriel Shoshani +1
This study examines the relaminarization of turbulent puffs in pipe flow using highly resolved direct numerical simulations at Reynolds numbers of 1880, 1900, and 1920. The exponen…
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…
Saddle-node bifurcation during the relaminarization of turbulent puffs in pipe
Basheer Ahmad Khan, Shai Arogeti, Oriel Shoshani +1
Turbulent puffs in a pipe persist for a long time before abruptly transitioning to laminar flow through viscous exponential decay. Direct numerical simulation results reveal a sadd…
Synchronization of E. coli bacteria moving in coupled wells
Aleksandre Japaridze, Victor Struijk, Kushal Swamy +4
Synchronization plays a crucial role in the dynamics of living organisms, from fireflies flashing in unison to pacemaker cells that jointly generate heartbeats. Uncovering the mech…
Amplitude stabilization in a synchronized nonlinear nanomechanical oscillator
Martial Defoort, Sébastien Hentz, Steven W. Shaw +1
In contrast to the well-known phenomenon of frequency stabilization in a synchronized noisy nonlinear oscillator, little is known about its amplitude stability. In this paper, we i…
Enhancing nonlinear damping by parametric-direct internal resonance
Ata Keşkekler, Oriel Shoshani, Martin Lee +3
Mechanical sources of nonlinear damping play a central role in modern physics, from solid-state physics to thermodynamics. The microscopic theory of mechanical dissipation [M. I .…
Anomalous dissipation of nanomechanical modes going through nonlinear resonance
O. Shoshani, S. W. Shaw, M. I. Dykman
We study nonlinear resonance of coupled modes in nano-mechanical systems. To reveal the qualitative features of the dynamics, we consider the limiting cases, where the results can…
