Decoding ionic conductivity and reordering in cation-disordered pyrochlores
author keywords: pyrochlores; solid-state ionics; molecular dynamics; energy materials; superionic conductors
TL;DR:
Using atomistic simulations on Gd2Zr2O7, it is shown that the anions engage in concerted hops to the neighbouring tetrahedral sites mostly along with the ⟨1 0 0⟩ direction while completely avoiding the octahedral sites, and both the distribution of available oxygen sites following random cation disorder and the probability of occupation of these sites are tracked.

Deducing Phonon Scattering from Normal Mode Excitations
SCIENTIFIC REPORTS, 9.
TL;DR:
This work adopts a set of real asymmetric normal mode amplitudes, and deduces that the energy exchanged from one mode to another in each elementary interaction is proportional to the frequency – a quantum-like restriction.

Exact diagonal representation of normal mode energy, occupation number, and heat current for phonon-dominated thermal transport
JOURNAL OF CHEMICAL PHYSICS, 151(10).
TL;DR:
This work casts the Hamiltonian, normal mode population, and heat current in an exactly diagonalizable representation using real normal mode amplitudes and shows that the use of real amplitudes obviates the need for a complex modal heat current while making the passage to second quantization more apparent.

A robust family of methods to compute the phonon dispersion curves based on the ratio of zero-time correlations of conjugate variables in the reciprocal space is presented and the ability of the ZTR methods to handle anharmonicity and phonon softening at high temperatures is illustrated.

Low Dimensional String-like Relaxation Underpins Superionic Conduction in Fluorites and Related Structures
SCIENTIFIC REPORTS, 7.
TL;DR:
This work provides weighty evidence for string-like dynamical structures that govern the fast ion conduction process in fluorites and shows that lower temperatures encourage the growth of longer but slowly relaxing strings and vice-versa - a direct manifestation of heterogeneous dynamics.

Mobility propagation and dynamic facilitation in superionic conductors
The Journal of Chemical Physics, 143(19), 194502.
TL;DR:
The mechanism of dynamic facilitation (DF) is demonstrated in two superionic conductors (CaF2 and UO2) using atomistic simulations and both the metrics quantifying DH and DF show remarkable correspondence implying that DF, in the framework of kinematically constrained models, underpins the heterogeneous dynamics in type II superioniconductors.
