Resonant excitation of Kelvin waves by interactions of subtropical Rossby waves and the zonal mean flow
Katharina M. Holube, Frank Lunkeit, Sergiy Vasylkevych +1
Equatorial Kelvin waves can be affected by subtropical Rossby wave dynamics. Previous research has demonstrated the Kelvin wave growth in response to subtropical forcing and the re…
A new construction of modified equations for variational integrators
Marcel Oliver, Sergiy Vasylkevych
The construction of modified equations is an important step in the backward error analysis of symplectic integrator for Hamiltonian systems. In the context of partial differential…
Excitation of mixed Rossby-gravity waves by wave-mean flow interactions on the sphere
Sándor István Mahó, Sergiy Vasylkevych, Nedjeljka Žagar
The equatorial mixed Rossby-gravity wave (MRGW) is an important contributor to tropical variability. Its excitation mechanism capable of explaining the observed MRGW variance peak…
Dynamics of ferromagnetic domain walls under extreme fields
Arseni Goussev, JM Robbins, Valeriy Slastikov +1
We report the existence of a new regime for domain wall motion in uniaxial and near-uniaxial ferromagnetic nanowires, characterised by applied magnetic fields sufficiently strong t…
Geodesic motion on the groups of diffeomorphisms with metric as geometric generalised Lagrangian mean theory
Marcel Oliver, Sergiy Vasylkevych
Generalized Lagrangian mean theories are used to analyze the interactions between mean flows and fluctuations, where the decomposition is based on a Lagrangian description of the f…
Geometric Lagrangian averaged Euler-Boussinesq and primitive equations
Gualtiero Badin, Marcel Oliver, Sergiy Vasylkevych
In this article we derive the equations for a rotating stratified fluid governed by inviscid Euler-Boussinesq and primitive equations that account for the effects of the perturbati…
