Weakly-Bound Excitation States in Crystals
Conference paper
Abstract
In the present paper it is shown that in crystals bound states of two elementary excitations (two phonons, a phonon and an electron) may be formed at arbitrarily weak interaction between them. This occurs in the vicinity of some special points in the quasimomentum space of the excitations.
