TL;DR: In this article, a microscopic picture connecting electronic structure and phonon anharmonicity in SnSe is provided, and offers new insights on how electron-phonon interactions may lead to the realization of ultralow thermal conductivity.

TL;DR: By combining inelastic neutron scattering measurements with density functional theory, fast lithium conductors were shown to have low lithium vibration frequency or low center of lithium phonon density of states as discussed by the authors.

TL;DR: In this article, the anharmonic phonon properties of SnSe in the $Pnma$ phase were investigated with a combination of experiments and first-principles simulations.

TL;DR: In this article, the authors present the results of energy and momentum-resolved scattering studies combined with first-princciples calculations and show that in the superionic phase of CuCrSe2, longwavelength acoustic phonons capable of heat conduction remain largely intact, whereas specific phonon quasiparticles dominated by the Cu ions break down as a result of anharmonicity and disorder.

TL;DR: In this article, the lattice dynamics and superionic diffusion in superionic conductors were investigated from energy and momentum-resolved neutron and X-ray scattering techniques, combined with first-principles calculations.
