Abstract:
I will begin with a discussion of particle-hole asymmetry in doped
Mott insulators and exact sum rules for one-particle spectroscopies:
STM and ARPES. I will then turn to a variational approach to gain
insight into the strongly correlated d-wave superconducting state of
the high Tc cuprates. After a quick review of earlier work on the
essential difference between pairing and phase coherence in doped Mott
insulators, I will describe new results. These include: the notion of
the underlying Fermi surface in the superconducting state;
characterizing the nodal quasiparticles; doping and temperature
dependence of the superfluid density and the insensit
