Vibrational lifetimes and viscoelastic properties of ultrastable glasses
Jan Grießer, Lars Pastewka
Amorphous solids are viscoelastic. They dissipate energy when deformed at finite rate and finite temperature. We here use analytic theory and molecular simulations to demonstrate t…
Yielding under compression and the polyamorphic transition in silicon
Jan Grießer, Gianpietro Moras, Lars Pastewka
We investigate the behavior of amorphous silicon under hydrostatic compression using molecular simulations. During compression, amorphous silicon undergoes a discontinuous nonequil…
Analytic elastic constants in molecular calculations: Finite strain, non-affine displacements, and many-body interatomic potentials
Jan Grießer, Lucas Frérot, Jonas A. Oldenstaedt +2
Elastic constants are among the most fundamental and important properties of solid materials, which is why they are routinely characterized in both experiments and simulations. Whi…
Surface lattice Green's functions for high-entropy alloys
Wolfram Georg Nöhring, Jan Grießer, Patrick Dondl +1
We study the surface elastic response of pure Ni, the random alloy FeNiCr and an average FeNiCr alloy in terms of the surface lattice Green's function. We propose a scheme for comp…
