    Uncertainty Principle Enhanced Pairing Correlations in Projected Fermi Systems Near Half Filling

    Get PDF
    We point out the curious phenomenon of order by projection in a class of lattice Fermi systems near half filling. Enhanced pairing correlations of extended s-wave Cooper pairs result from the process of projecting out s-wave Cooper pairs, with negligible effect on the ground state energy. The Hubbard model is a particularly nice example of the above phenomenon, which is revealed with the use of rigorous inequalities including the Uncertainty Principle Inequality. In addition, we present numerical evidence that at half filling, a related but simplified model shows ODLRO of extended s-wave Cooper pairs.Comment: RevTex 11 pages + 1 ps figure.

    The Lyman H. Butterfield Award is presented this year to Helen R. Deese. With this award the Association for Documentary Editing recognizes, first and foremost, Professor Deese’s achievements as a scholar who works on both sides of our putative divide, producing acclaimed editions of both literary and historical texts. We also recognize her generous service to the Association over many years as a member of its committees and Council, a presenter at annual meetings, an author in Documentary Editing, and a thoughtful contributor to our ongoing discussions of editorial theory and practice
