Excitonic instability and unconventional pairing in the nodal-line materials ZrSiS and ZrSiSe
M. M. Scherer, C. Honerkamp, A. N. Rudenko +3
We use a functional renormalization group (fRG) approach to investigate potential interaction-induced instabilities in a two-dimensional model for the Dirac nodal-line materials Zr…
Exchange interactions in transition metal oxides: The role of oxygen spin polarization
R. Logemann, A. N. Rudenko, M. I. Katsnelson +1
Magnetism of transition metal (TM) oxides is usually described in terms of the Heisenberg model, with orientation-independent interactions between the spins. However, the applicabi…
Role of direct exchange and Dzyaloshinskii-Moriya interactions in magnetic properties of graphene derivatives: CF and CH
V. V. Mazurenko, A. N. Rudenko, S. A. Nikolaev +3
According to the Lieb's theorem the ferromagnetic interaction in graphene-based materials with bipartite lattice is a result of disbalance between the number of sites available for…
Correlation effects in insulating surface nanostructures
V. V. Mazurenko, S. N. Iskakov, A. N. Rudenko +4
We study the role of static and dynamical Coulomb correlation effects on the electronic and magnetic properties of individual Mn, Fe and Co adatoms deposited on the CuN surface. Fo…
Orbital-selective conductance of Co adatom on the Pt(111) surface
V. V. Mazurenko, S. N. Iskakov, M. V. Valentyuk +2
We propose an orbital-selective model for the transport and magnetic properties of the individual Co impurity deposited on the Pt(111). Using the combination of the Anderson-type H…
Renormalized spectral function for Co adatom on the Pt(111) surface
V. V. Mazurenko, S. N. Iskakov, A. N. Rudenko +2
The strong Coulomb correlations effects in the electronic structure of magnetic Co adatom on the Pt(111) surface have been investigated. Using a realistic five d-orbital impurity A…
