Determining the underlying Fermi surface of strongly correlated superconductors
Claudius Gros, Bernhard Edegger, V. N. Muthukumar +1
The notion of a Fermi surface (FS) is one of the most ingenious concepts developed by solid state physicists during the past century. It plays a central role in our understanding o…
Electronic structure of strongly correlated d-wave superconductors
Bernhard Edegger, V. N. Muthukumar, Claudius Gros +1
We study the electronic structure of a strongly correlated d-wave superconducting state. Combining a renormalized mean field theory with direct calculation of matrix elements, we o…
Particle number renormalization in almost half filled Mott Hubbard superconductors
Bernhard Edegger, Noboru Fukushima, Claudius Gros +1
The effects of the Gutzwiller projection on a BCS wave function with varying particle number are considered. We show that a fugacity factor has to be introduced in these wave funct…
