Theory for Dynamical Short Range Order and Fermi Surface Volume in Strongly Correlated Systems
J. Schmalian, M. Langer, S. Grabowski +1
Using the fluctuation exchange approximation of the one band Hubbard model, we discuss the origin of the changing Fermi surface volume in underdoped cuprate systems due to the tran…

Theory for the excitation spectrum of High-T$_c superconductors : quasiparticle dispersion and shadows of the Fermi surface
M. Langer, J. Schmalian, S. Grabowski +1
Using a new method for the solution of the FLEX-equations, which allows the determination of the self energy of the Hubbard model on the real frequency axis, we…
