Kink Structure in the Quasiparticle Band of Doped Hubbard Systems
Yoshiro Kakehashi, Peter Fulde
By making use of the self-consistent projection operator method with high-momentum and high-energy resolutions, we find a kink structure in the quasiparticle excitation spectrum of…

Marginal Fermi Liquid Theory in the Hubbard Model
Y. Kakehashi, P. Fulde
We find Marginal Fermi Liquid (MFL) like behavior in the Hubbard model on a square lattice for a range of hole doping and on-site interaction parameter U. Thereby we use a self-con…
