Dual-fermion approach to the Anderson-Hubbard model

P. Haase, S. -X. Yang, T. Pruschke +2

We apply the recently developed dual fermion algorithm for disordered interacting systems to the Anderson-Hubbard model. This algorithm is compared with dynamical cluster approxima…

Optical conductivity of the Hubbard chain away from half filling

Alexander C. Tiegel, Thomas Veness, Piet E. Dargel +4

We consider the optical conductivity in the metallic phase of the one-dimensional Hubbard model. Our results focus on the vicinity of half filling and the frequency regime…

Dynamical properties of the sine-Gordon quantum spin magnet Cu-PM at zero and finite temperature

Alexander C. Tiegel, Andreas Honecker, Thomas Pruschke +4

The material copper pyrimidine dinitrate (Cu-PM) is a quasi-one-dimensional spin system described by the spin-1/2 XXZ Heisenberg antiferromagnet with Dzyaloshinskii-Moriya interact…

Reduced density-matrix functionals applied to the Hubbard dimer

Ebad Kamil, Robert Schade, Thomas Pruschke +1

Common density-matrix functionals, the Müller and the power functional, have been benchmarked for the half-filled Hubbard dimer, which allows to model the bond dissociation problem…

Mott Quantum Criticality in the Anisotropic 2D Hubbard Model

Benjamin Lenz, Salvatore R. Manmana, Thomas Pruschke +2

We present evidence for Mott quantum criticality in an anisotropic two-dimensional system of coupled Hubbard chains at half-filling. In this scenario emerging from variational clus…

Fine structure of spectra in the antiferromagnetic phase of the Kondo lattice model

Ziga Osolin, Thomas Pruschke, Rok Zitko

We study the antiferromagnetic phase of the Kondo lattice model on bipartite lattices at half-filling using the dynamical mean-field theory with numerical renormalization group as…
