Towards a global theory for the high T_c cuprates: Explanation of the puzzling optical properties
J. Ashkenazi
A theory has been worked out for the cuprates, which is based on the major features of their first-principles-derived electronic structure, including the contribution of a large-U…
Stripe-like Inhomogeneities, Coherence, and the Physics of the High Tc Cuprates
J. Ashkenazi
The carriers in the high-Tc cuprates are found to be polaron-like "stripons" carrying charge and located in stripe-like inhomogeneities, "quasi-electrons" carrying charge and spin,…
Stripe-Like Inhomogeneities, Carriers, and BCS-BEC Crossover in the High-Tc Cuprates
J. Ashkenazi
Considering both "large-U" and "small-U" orbitals, it is found that the carriers of the high-Tc cuprates are polaron-like "stripons" carrying charge and located on stripe-like inho…
Stripes, Electron-Like and Polaron-Like Carriers, and High-T_c in the Cuprates
J. Ashkenazi
Both "large-U" and "small-U" orbitals are used to study the electronic structure of the high-T_c cuprates. A striped structure with three types of carriers are induced, polaron-lik…
