Ferromagnetic instability in itinerant fcc lattice electron systems with higher order van Hove singularities: Functional renormalization group study
P. A. Igoshev, A. A. Katanin
We investigate the possibility of ferromagnetic ordering in the non-degenerate Hubbard model on the face-centered cubic lattice within the functional renormalization group techniqu…

Giant density-of-states van Hove singularities in the face-centered cubic lattice
P. A. Igoshev, V. Yu. Irkhin
All van Hove singularities in the density of states (DOS) of face-centered cubic lattice in the nearest and next-nearest neighbour approximation, focusing on higher-order ones, are…

Electron Spectrum Topology and Giant Density-of-States Singularities in Cubic Lattices
P. A. Igoshev, V. Yu. Irkhin
The topology of isoenergetic surfaces in reciprocal space for simple (sc), body-centered (bcc), and face-centered (fcc) cubic lattices is investigated in detail in the tight-bindin…
