What is a polaron in condensed matter physics?

Definition of Polaron A polaron is a quasiparticle that arises from the interaction between a charge carrier, usually an electron, and the lattice vibrations (phonons) within a solid material. This interaction causes a localized distortion in the crystal lattice surrounding the electron, effectively coupling the electron with a cloud of phonons. As a result, the […]
