Contributions to the mixed-alkali effect in molecular dynamics simulations of alkali silicate glasses
Heiko Lammert, Andreas Heuer
The mixed-alkali effect on the cation dynamics in silicate glasses is analyzed via molecular dynamics simulations. Observations suggest a description of the dynamics in terms of st…
Does the potential energy landscape of a supercooled liquid resemble a collection of traps?
A. Heuer, B. Doliwa, A. Saksaengwijit
It is analyzed whether the potential energy landscape of a glass-forming system can be effectively mapped on a random model which is described in statistical terms. For this purpos…
Nonlinear Ionic Conductivity of Thin Solid Electrolyte Samples: Comparison between Theory and Experiment
Andreas Heuer, Sevi Murugavel, Bernhard Roling
Nonlinear conductivity effects are studied experimentally and theoretically for thin samples of disordered ionic conductors. Following previous work in this field the {\it experime…
Coupling of ion and network dynamics in lithium silicate glasses: a computer study
Magnus Kunow, Andreas Heuer
We present a detailed analysis of the ion hopping dynamics and the related nearby oxygen dynamics in a lithium meta silicate glass via molecular dynamics simulation. For this purpo…
