POLARON
Polaron
A polaron is a quasiparticle used in condensed matter physics used to understand the interactions between electrons and atoms in a solid material. The polaron concept was first proposed by Lev Landau in 1933 to describe an electron moving in a dielectric crystal where the atom move from their equilibrium positions to effectively screen the charge of an electron, known as a phonon cloud. This lowers the electron mobility and increases the electron's effective mass.The above text is a snippet from Wikipedia: Polaron
