Oneparticle spectral function singularities in a onedimensional gas of spin1/2 fermions with repulsive deltafunction interaction
/ Čadež, T. ; Nemati, S. ; Carmelo, J.M.P.
The momentum, fermionic density, spin density, and interaction dependencies of the exponents that control the (k,ω) plane singular features of the onefermion spectral functions of a onedimensional gas of spin1/2 fermions with repulsive deltafunction interaction both at zero and finite magnetic field are studied in detail.

Pseudofermion dynamical theory for the spin dynamical correlation functions of the halffilled 1D Hubbard model
/ Carmelo, J.M.P. ; Čadež, T.
A modified version of the metallicphase pseudofermion dynamical theory (PDT) of the 1D Hubbard model is introduced for the spin dynamical correlation functions of the halffilled 1D Hubbard model Mott–Hubbard phase. [...]
