Interpretation of the vibrational spectra of glassy polymers using coarse-grained simulations
Rico Milkus, Christopher Ness, Vladimir V. Palyulin +3
The structure and vibrational density of states (VDOS) of polymer glasses are investigated using numerical simulations based on the classical Kremer-Grest bead-spring model. We foc…
Parameter-free predictions of the viscoelastic response of glassy polymers from non-affine lattice dynamics
Vladimir V. Palyulin, Christopher Ness, Rico Milkus +3
We study the viscoelastic response of amorphous polymers using theory and simulations. By accounting for internal stresses and considering instantaneous normal modes (INMs) within…
Nonmonotonic dependence of polymer glass mechanical response on chain bending stiffness
Christopher Ness, Vladimir V. Palyulin, Rico Milkus +3
We investigate the mechanical properties of amorphous polymers by means of coarse-grained simulations and nonaffine lattice dynamics theory. A small increase of polymer chain bendi…
Non-affine lattice dynamics of defective fcc crystals
Johannes Krausser, Rico Milkus, Alessio Zaccone
The mechanical, thermal and vibrational properties of defective crystals are important in many different contexts, from metallurgy and solid-state physics to, more recently, soft m…
Atomic-scale origin of dynamic viscoelastic response and creep in disordered solids
Rico Milkus, Alessio Zaccone
Viscoelasticity has been described since the time of Maxwell as an interpolation of purely viscous and purely elastic response, but its microscopic atomic-level mechanism in solids…
Direct link between boson-peak modes and dielectric -relaxation in glasses
B. Cui, R. Milkus, A. Zaccone
We compute the dielectric response of glasses starting from a microscopic system-bath Hamiltonian of the Zwanzig-Caldeira-Leggett type and using an ansatz from kinetic theory for t…
The relation between stretched-exponential relaxation and the vibrational density of states in glassy disordered systems
B. Cui, R. Milkus, A. Zaccone
Amorphous solids or glasses are known to exhibit stretched-exponential decay over broad time intervals in several of their macroscopic observables: intermediate scattering function…
