Named for one of the winners of the 1972 Nobel Prize in Physics, FTP, identify this phenomenon important in the BCS theory of superconductivity, a type of coupling of electrons.
Electron-like or hole-like quasiparticles can be created when these are bombarded by X-rays, making them useful for high precision detection of X-ray energy.  First proposed by Froehlich, they were experimentally corroborated by the isotope effect and the evidence for a condensation to a boson-like state at the superconducting transition temperature.  They are caused by the exchange of phonons.
