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…
A simple harmonic model as a caricature for mismatch and relaxation effects for ion hopping dynamics in solid electrolytes
Magnus Kunow, Andreas Heuer
We formulate a simple harmonic mean-field model with N+1 particles and analyse the relaxation processes following a jump of one of these particles. Either the particle can jump bac…
Complete identification of alkali sites in ion conducting lithium silicate glasses: a computer study of ion dynamics
Heiko Lammert, Magnus Kunow, Andreas Heuer
The available sites for ions in a typical disordered ionic conductor are determined. For this purpose we devised a straightforward algorithm which via cluster analysis identifies t…
Backward correlations and dynamic heterogeneities: a computer study of ion dynamics
Andreas Heuer, Magnus Kunow, Michael Vogel +1
We analyse the correlated back and forth dynamics and dynamic heterogeneities, i.e. the presence of fast and slow ions, for a lithium metasilicate system via computer simulations.…
Characterization of the complex ion dynamics in lithium silicate glasses via computer simulations
Andreas Heuer, Magnus Kunow, Michael Vogel +1
We present results of molecular dynamics simulations on lithium metasilicate over a broad range of temperatures for which the silicate network is frozen in but the lithium ions can…
