Multi-channel fluctuating field approach to competing instabilities in interacting electronic systems
E. Linnér, A. I. Lichtenstein, S. Biermann +1
Systems with strong electronic Coulomb correlations often display rich phase diagrams exhibiting different ordered phases involving spin, charge, or orbital degrees of freedom. The…
Reconstruction of classical skyrmions from Anderson towers: quantum Darwinism in action
O. M. Sotnikov, E. A. Stepanov, M. I. Katsnelson +2
The development of the quantum skyrmion concept is aimed at expanding the scope of the fundamental research and practical applications for classical topologically-protected magneti…
Quantitative theory of magnetic interactions in solids
Attila Szilva, Yaroslav Kvashnin, Evgeny A. Stepanov +4
In this report we review the method of explicit calculations of interatomic exchange interactions of magnetic materials. This involves exchange mechanisms normally referred to as H…
Multi-band D-TRILEX approach to materials with strong electronic correlations
Matteo Vandelli, Josef Kaufmann, Mohammed El-Nabulsi +3
We present the multi-band dual triply irreducible local expansion (D-TRILEX) approach to interacting electronic systems and discuss its numerical implementation. This method is des…
Eliminating Orbital Selectivity from the Metal-Insulator Transition by Strong Magnetic Fluctuations
Evgeny A. Stepanov
The orbital-selective electronic behavior is one of the most remarkable manifestations of strong electronic correlations in multi-orbital systems. A prominent example is the orbita…
Extended regime of coexisting metallic and insulating phases in a two-orbital electronic system
M. Vandelli, J. Kaufmann, V. Harkov +3
We investigate the metal-to-insulator phase transition driven by the density-density electronic interaction in the quarter-filled model on a cubic lattice with two orbitals split b…
