Abstract

A simple model of the crystals, the anharmonic linear chain with nearest neighbour interaction will be investigated briefly in the first order of the self-consistent phonon field theory (SCPT). In this case we can obtain a simple explicit solution which helps to clarify some aspects of the SCPT and the phenomenon of the lattice instability.
