From Slater to Mott-Heisenberg physics: The antiferromagnetic phase of the Hubbard model
Thomas Pruschke, Robert Zitzler
We study the optical conductivity of the one-band Hubbard model in the Néel state at half filling at T=0 using the dynamical mean-field theory. For small values of the Coulomb para…
Phase diagram of the frustrated Hubbard model
R. Zitzler, N. Tong, Th. Pruschke +1
The Mott-Hubbard metal-insulator transition in the paramagnetic phase of the one-band Hubbard model has long been used to describe similar features in real materials like VO$_3…
Kondo screening in d-wave superconductors in a Zeeman field and implications for STM spectra of Zn-doped cuprates
Matthias Vojta, Robert Zitzler, Ralf Bulla +1
We consider the screening of an impurity moment in a d-wave superconductor under the influence of a Zeeman magnetic field. Using the Numerical Renormalization Group technique, we i…
Magnetism and Phase Separation in the Ground State of the Hubbard Model
R. Zitzler, Th. Pruschke, R. Bulla
We discuss the ground state magnetic phase diagram of the Hubbard model off half filling within the dynamical mean-field theory. The effective single-impurity Anderson model is sol…
