Apparent nonlinear damping triggered by quantum fluctuations [PDF]

open access: yesNature Communications, 2023
Nonlinear damping, the change in damping rate with the amplitude of oscillations plays an important role in many electrical, mechanical and even biological oscillators. In novel technologies such as carbon nanotubes, graphene membranes or superconducting

Nonlinear damping and quasi-linear modelling [PDF]

open access: yesPhilosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2015
The mechanism of energy dissipation in mechanical systems is often nonlinear. Even though there may be other forms of nonlinearity in the dynamics, nonlinear damping is the dominant source of nonlinearity in a number of practical systems. The analysis of such systems is simplified by the fact that they show no jump or bifurcation behaviour,

On the Theory of Nonlinear Landau Damping

open access: yesSymmetry, 2022
An exact solution of the collisionless time-dependent Vlasov equation is found. For the first time in a century, an analytical solution to the one-dimensional time-dependent Vlasov–Boltzmann equation has been found. It has been found that instead of the widely discussed damping, waves are subject to instability.
