  • Response to D. J. Scalapino’s E-Letter

    The concluding sentence of D. J. Scalapino’s E-Letter leaves the unfortunate impression that we differ fundamentally on the basics of the cuprate problem, whereas in the usual sense of the words he introduces no "glue" at all: He is dealing entirely with the Hubbard model—or, as he would agree is equivalent, the t-J model—and in that sense he has introduced no exotic physics at all independent of the two strong interac...

  • Pairing Glue in the Cuprate Superconductors

    While there is a growing consensus that superconductivity in the high Tc cuprates arises from strong short-range Coulomb interactions between electrons rather than the traditional electron-phonon interaction, the precise nature of the pairing interaction remains controversial (1). This is the case even among those who agree that the essential physics of the cuprates is contained in the Hubbard model...
