We investigate detailed lattice dynamics of copper halides CuX (X=Cl, Br, I) using neutron inelastic scattering measurements and ab-initio calculations aimed at a comparative study of their thermal expansion behavior. We identify the low energy phono

We have performed ab-initio lattice dynamics and molecular dynamics studies of Li2X (X=O, S and Se) to understand the ionic conduction in these compounds. The inelastic neutron scattering measurements on Li2O have been performed across its superionic

Cu2ZnSnS4 is a p-type semiconductor that has been seen as a possible replacement for SnSe, Cu (In,Ga)Se2 etc. in thin film solar cells, due to non-toxicity and natural abundance of their constituent elements. Polycrystalline Cu2ZnSnS4 samples (kester

The hydration and ammonization of $\mathrm{Zr}{\mathrm{W}}_{2}{\mathrm{O}}_{8}$ is known to lead to positive and negative thermal expansion behavior, respectively. We report ab initio calculations to understand this anomalous behavior. We identify th

In order to identify and quantitatively analyze the anharmonicity of phonons relevant to the anomalous thermal expansion in the Ih phase of ice, we performed neutron inelastic scattering measurements of the phonon spectrum as a function of pressure u
