TL;DR: A microscopic state for the vortex phase of BSCO superconductors is proposed, where around the vortex core or above H(c2), the d wave hole pairs form a checkerboard localized in the antiferromagnetic background.
Abstract: We propose a microscopic state for the vortex phase of BSCO superconductors. Around the vortex core or above H-c2, the d wave hole pairs form a checkerboard localized in the antiferromagnetic background. We discuss this theory in connection with recent ST

TL;DR: In this paper, the authors distinguish between the BCS model and the more general BCS theory, and carefully distinguish between BCS and the general theory of superconductivity, which is described well by the Bardeen-Cooper-Schrieffer model.
Abstract: Investigations of rare earth, Aactinide, organic and oxide compounds have yielded several new classes of exotic superconductors. These include magnetically ordered superconductors, A15 superconductors, buckyball superconductors, heavy‐electron superconductors, organic superconductors and high‐Tc oxide superconductors. These materials have properties significantly different from those of conventional superconductors such as Al and Zn, which are described well by the Bardeen‐Cooper‐Schrieffer model of superconductivity. We carefully distinguish between the BCS model and the more general BCS theory. In the BCS theory superconductivity arises, loosely speaking, from electron pairs that behave essentially as bosons and undergo macroscopic condensation to the lowest energy state at the critical temperature Tc The BCS model, presented in 1957, further specifies that the pairing is mediated by exchange of quantized lattice vibrations (phonons) between the electrons, yielding pairs with zero spin S (spin singlet) ...

TL;DR: The experimentally observed two electronic bands in the infrared spectrum can be identified in terms of the interplay between the electron correlation and electron-phonon interaction resolving the long standing mystery of the midinfrared band.
Abstract: The charge dynamics in weakly hole doped high temperature superconductors is studied in terms of the accurate numerical solution to a model of a single hole interacting with a quantum lattice in an antiferromagnetic background, and accurate far-infrared ellipsometry measurements. The experimentally observed two electronic bands in the infrared spectrum can be identified in terms of the interplay between the electron correlation and electron-phonon interaction resolving the long standing mystery of the midinfrared band.
