Abstract
A simple model for describing the electron-photon coupling in a strongly correlated electron-gas is introduced. A general framework for computing the dynamical matrix is presented and a number of electronic mean field states in the t-J model is considered. The two different choices of quasi-particle statistics are shown to result in very different stability behaviour at finite doping. The connection to the tetragonal to orthorhombic structural phasetransition in (La, Ba){sub 2}CuO{sub 4} and other superconducting cuprates is discussed. (orig.).
