In this work, renormalization of effective mass of an electron due to small polaron formation is studied within the framework of Extended Holstein model. It is assumed that electron moves along one-dimensional chain of ions and interacts with ions vibrations of neighboring chain via long-range density–displacement type force. By means of exact calculations, renormalized mass of nonadiabatic small polaron is obtained at strong coupling limit. Obtained results compared with those of small polaron mass of ordinary Holstein model. An effect of ions vibrations polarization on small polaron mass is addressed.
