Breakdown of the Luttinger sum rule within the Mott-Hubbard insulator
J. Kokalj, P. Prelovsek
The validity of the Luttinger sum rule is investigated within the prototype tight-binding model of interacting fermions in one dimension, i.e., the t-V model including the next-nea…

Violation of the Luttinger sum rule within the Hubbard model on a triangular lattice
J. Kokalj, P. Prelovsek
The frequency-moment expansion method is developed to analyze the validity of the Luttinger sum rule within the Mott-Hubbard insulator, as represented by the generalized Hubbard mo…

Luttinger sum rule for finite systems of correlated electrons
J. Kokalj, P. Prelovsek
The validity of the Luttinger sum rule is considered for finite systems of interacting electrons, where the Fermi volume is determined by location of zeroes of Green's function. It…
