Properties of anisotropic magnetic impurities on surfaces
Rok Zitko, Robert Peters, Thomas Pruschke
Using numerical renormalization group techniques, we study static and dynamic properties of a family of single-channel Kondo impurity models with axial magnetic anisotropy …
Half-filled Hubbard Model on a Bethe lattice with next-nearest neighbor hopping
Robert Peters, Thomas Pruschke
We study the interplay between Néel-antiferromagnetism and the paramagnetic metal-insulator-transition (PMIT) on a Bethe lattice with nearest and next-nearest eighbor hopping …
A finite-frequency functional RG approach to the single impurity Anderson model
C. Karrasch, R. Hedden, R. Peters +3
We use the Matsubara functional renormalization group (FRG) to describe electronic correlations within the single impurity Anderson model. In contrast to standard FRG calculations,…
Magnetic properties of the extended periodic Anderson model
Akihisa Koga, Norio Kawakami, Robert Peters +1
We study magnetic properties of the extended periodic Anderson model, which includes electron correlations within and between itinerant and localized bands. By combining dynamical…
