1. One-particle spectral function singularities in a one-dimensional gas of spin-1/2 fermions with repulsive delta-function 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 one-fermion spectral functions of a one-dimensional gas of spin-1/2 fermions with repulsive delta-function interaction both at zero and finite magnetic field are studied in detail.

2. One-electron singular spectral features of the 1D Hubbard model at finite magnetic field / Carmelo, J.M.P. ; Čadež, T.
The momentum, electronic density, spin density, and interaction dependences of the exponents that control the (k,ω) -plane singular features of the σ=↑,↓ one-electron spectral functions of the 1D Hubbard model at finite magnetic field are studied. [...]

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