Metastable energy strata in numerical discretizations of weakly nonlinear wave equations
Ludwig Gauckler, Daniel Weiss
The quadratic nonlinear wave equation on a one-dimensional torus with small initial values located in a single Fourier mode is considered. In this situation, the formation of metas…

Numerical integrators for motion under a strong constraining force
Christian Lubich, Daniel Weiss
This paper deals with the numerical integration of Hamiltonian systems in which a stiff anharmonic potential causes highly oscillatory solution behavior with solution-dependent fre…
