Abstract
Theoretical calculations [1, 2], and a variety of experimental data [3] support the assumption that the high-Tc cuprates are characterized by dynamical stripe-like inhomogeneities, where narrow charged stripes form antiphase domain walls separating wider antiferromagnetic (AF) stripes. Experimental observations have been pointing to the presence of both itinerant and almost localized (or polaron-like) carriers in the cuprates. First-principles calculations [4] support an approach based on the existence of both large-U and small-U orbitals in the vicinity of the Fermi level (EF).
