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.

Absence of ballistic charge transport in the halffilled 1D Hubbard model
/ Carmelo, J.M.P. ; Nemati, S. ; Prosen, T.
Whether in the thermodynamic limit of lattice length L→∞ , hole concentration mηz=−2Sηz/L=1−ne→0 , nonzero temperature T>0 , and U/t>0 the charge stiffness of the 1D Hubbard model with first neighbor transfer integral t and onsite repulsion U is finite or vanishes and thus whether there is or there is no ballistic charge transport, respectively, remains an unsolved and controversial issue, as different approaches yield contradictory results.

Absence of hightemperature ballistic transport in the spin1/2 XXX chain within the grandcanonical ensemble
/ Carmelo, J.M.P. ; Prosen, T.
Whether in the thermodynamic limit, vanishing magnetic field h→0 , and nonzero temperature the spin stiffness of the spin1/2 XXX Heisenberg chain is finite or vanishes within the grandcanonical ensemble remains an unsolved and controversial issue, as different approaches yield contradictory results.

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. [...]
