Description

In the framework of the extended Hubbard model (copper-oxygen and oxygen-oxygen hopping) the energy and effective mass of a mobile hole is expressed in terms of hopping parameters and the correaltors between spins of the background . Due to interaction of the mobile hole with localized holes, its effective mass increases about four times. (orig.)
