FPU physics with nanomechanical graphene resonators: intrinsic relaxation and thermalization from flexural mode coupling
Daniel Midtvedt, Zenan Qi, Alexander Croy +2
Thermalization in nonlinear systems is a central concept in statistical mechanics and has been extensively studied theoretically since the seminal work of Fermi, Pasta and Ulam (FP…
Frequency tuning, nonlinearities and mode coupling in circular graphene resonators
A. M. Eriksson, D. Midtvedt, A. Croy +1
We study circular nanomechanical graphene resonators by means of continuum elasticity theory, treating them as membranes. We derive dynamic equations for the flexural mode amplitud…
Nonlinear-dissipation-induced Entanglement of Coupled Nonlinear Oscillators
Aurora Voje, Andreas Isacsson, Alexander Croy
The quantum dynamics of two weakly coupled nonlinear oscillators is analytically and numerically investigated in the context of nonlinear dissipation. The latter facilitates the cr…
