THIS TUTORIAL IS FOR INTERNAL USE ONLY
In this tutorial we show how to generate Thermal Lines[1]. and Special Displacements[2] with YamboPy and then use them
to calculate different properties at finite temperature.
We will start from phonon calculations, interpolation of phonon modes, generation
of thermal lines/special displacements supercells and finally calculation of electronic properties ad finite temperature.
This tutorial requires a deep knowledge of phonon calculations, and the study of Refs.[1],[2].
