The Placzek transient refers to a short-lived, non-equilibrium state that occurs in a physical system when it undergoes rapid changes, commonly associated with systems that have a coupled thermal or mechanical response, such as in phonon-electron interactions in solids. The term is often encountered in the context of condensed matter physics, particularly in studies dealing with thermal transport and nonequilibrium dynamics.
