Feshbach shape resonance for high Tc pairing in superlattices of quantum stripes and quantum wells abstract
The Feshbach shape resonances in the interband pairing in superconducting superlattices of quantum wells or quantum stripes is shown to provide the mechanism for high Tc superconductivity. This mechanism provides the Tc amplification driven by the architecture of material: superlattices of quantum wells (intercalated graphite or diborides) and superlattices of quantum stripes (doped high Tc cuprate perovskites) where the chemical potential is tuned to a Van Hove-Lifshitz singularity (vHs) in the electronicenergy spectrum of the superlattice associated with the change of the Fermi surface dimensionality in one of the subbands
