Second Wilson number from third-order perturbation theory for the symmetric single-impurity Kondo model at low temperatures
Kevin Bauerbach, Florian Gebhard
We determine the impurity-induced free energy and the impurity-induced zero-field susceptibility of the symmetric single-impurity Kondo model from weak-coupling perturbation theory…

Generic Mott-Hubbard phase diagram for extended Hubbard models without Umklapp scattering
Florian Gebhard, Kevin Bauerbach, Örs Legeza
We determine the ground-state phase diagram for the 1/r-Hubbard model with repulsive nearest-neighbor interaction at half band-filling using the density-matrix renormalization grou…

Accurate localization of Kosterlitz-Thouless-type quantum phase transitions for one-dimensional spinless fermions
Florian Gebhard, Kevin Bauerbach, Örs Legeza
We investigate the charge-density wave (CDW) transition for one-dimensional spinless fermions at half band-filling with nearest-neighbor electron transfer amplitude and interac…
