Influence of the coordination defects on the dynamics and the potential energy landscape of two-dimensional silica
Projesh Kumar Roy, Andreas Heuer
The main cause of the fragile-to-strong crossover of 3D silica was previously attributed to the presence of a low energy cutoff in the potential energy landscape. The important que…
Relating local structures, energies, and occurrence probabilities in a two-dimensional silica network
Projesh Kumar Roy, Andreas Heuer
Recently, it became possible to experimentally generate and characterize a very thin silica system on a substrate which can be basically described as a 2D random network. The key s…
Ring statistics in 2D-silica: effective temperatures in equilibrium
Projesh Kumar Roy, Andreas Heuer
The thermodynamic properties of subsystems in strong interaction with the neighborhood can largely differ from the standard behavior. Here we study the thermodynamic properties of…
The frequency-dependence of nonlinear conductivity in disordered systems: an analytically solvable model
Clara Mattner, Bernhard Roling, Andreas Heuer
For the hopping dynamics in a one-dimensional model, containing energy and barrier disorder, we determine the linear and nonlinear response to an external field for arbitrary exter…
Can the dynamics of an atomic glass-forming system be described as a continuous time random walk?
Oliver Rubner, Andreas Heuer
We show that the dynamics of supercooled liquids, analyzed from computer simulations of the binary mixture Lennard-Jones system, can be described in terms of a continuous time rand…
Microscopic description of the low-temperature anomalies in silica and lithium silicate via computer simulations
J. Reinisch, A. Heuer
Information about the nature of the low-temperature anomalies and in particular the properties of the tunneling systems in silica and lithium silica glasses are revealed via comput…
