Підтримка: I have first of all to acknowledge my long-term collaborator Nai-Phuan Ong, for the innumerable times he has helped me with experimental know-how and theoretical comments. I should also acknowledge my collaborators in the plain vanilla exercise, T.M. Rice, P.A. Lee, Mohit Randeria, Nandini Trivedi and Fu-Chun Zhang, as well as others who were involved in finding the solution 17 years too early: Claudius Gros and Gabi Kotliar. Others who have helped keep my mind clear about experimental data have been Doug Bonn, Nicole Bontemps, Bernhard Keimer, Seamus Davis, Mike Norman, J.-C. Campuzano, Tom Timusk, Kam Moler; this is only a tiny fraction of the totality of individuals who have been helpful. But none of the above need take any responsibility for what I say here. Finally, there is my good friend and sounding board, V. Muthukumar.

Present status of the theory of the high-Tc cuprates

Анотація:

The Gutzwiller projected mean-field theory, also called plain vanilla or renormalized meanfield theory, is explained and its successes and possible extensions in describing the phenomenology of the cuprate superconductors are discussed. Throughout, we emphasize that while this is a Hartree—Fock based BCS theory, it embodies fundamental differences from conventional perturbative many body theory which may be characterized by calling it a theory of the doped Mott insulator.
