LETTER TO THE EDITOR

ANHARMONIC EFFECTS AND POLARON FORMATION IN THE COPPER OXIDES

Received 9 June 1994

We discuss polaron formation in anharmonic lattice. Expanding the local lattice distortion into coherent Glauber states, from the minimum energy condition we determine the hybridization amplitude renormalization and discuss its influence on polaron mobility and magnetic interactions.
