<br /> Hi
</div>
<div>I want to know what is the relation between phonon calculations and
temperature? I know that density & external potentials depend on ion
displacements, but I couldn't understand how does code connect these
displacements to temperature? also I want to know that whether ionic
displacements cause any ripples or roughness in the structure of sample or
not?
