An Adaptive Fourier Spectral Method for the Vlasov-Poisson system
Seung Yeon Cho, Giovanni Russo
The paper introduces an adaptive Fourier spectral method with high-order time splitting to dynamically expand the wavenumber domain and avoid artificial filtering when simulating t…
Activation and Avalanche Length Scales in the Finite-Temperature Creep of an Elastic Interface
Giovanni Russo, Ezequiel E. Ferrero, Alejandro B. Kolton +2
We investigate the creep dynamics of a driven elastic line at finite temperature, well below the depinning threshold. We show that creep is governed by two distinct length scales.…
An efficient implicit scheme for the multimaterial Euler equations in Lagrangian coordinates
Simone Chiocchetti, Giovanni Russo
Stratified fluids composed of a sequence of alternate layers show interesting macroscopic properties, which may be quite different from those of the individual constituent fluids.…
A quantitative comparison of high-order asymptotic-preserving and asymptotically-accurate IMEX methods for the Euler equations with non-ideal gases
Giuseppe Orlando, Sebastiano Boscarino, Giovanni Russo
We present a quantitative comparison between two different Implicit-Explicit Runge-Kutta (IMEX-RK) approaches for the Euler equations of gas dynamics, specifically tailored for the…
