Non-adiabatic effects lead to the breakdown of the semi-classical phonon picture
23 Lug , 2024 - NEWS
“Despite the fact that the phonon concept is one of the most widely used, studied, reviewed concepts in modern condensed matter, some, even basic, properties are still debated. In this contribution I will discuss, trying to shed light on, some of the main open questions. Density-Functional Perturbation Theory (DFPT) is routinely used to calculate non-adiabatic […]
