One- and two-channel Kondo model with logarithmic Van Hove singularity: a numerical renormalization group solution
A. K. Zhuravlev, A. O. Anokhin, V. Yu. Irkhin
Simple scaling consideration and NRG solution of the one- and two-channel Kondo model in the presence of a logarithmic Van Hove singularity at the Fermi level is given. The tempera…
The nature of the ferromagnetic ground state in the Mn4 molecular magnet
S. V. Streltsov, Z. V. Pchelkina, D. I. Khomskii +6
Using ab initio band structure and model calculations we studied magnetic properties of one of the Mn molecular magnets (Mn4(hmp)6), where two types of the Mn ions exist: Mn3+…
Exchange Interactions in a Dinuclear Manganese (II) Complex with Cyanopyridine-N-oxide Bridging Ligands
A. S. Markosyan, I. Yu. Gaidukova, A. V. Ruchkin +5
The structure and magnetic properties of oligonuclear manganese complex [Mn(hfa)2cpo]2 (where hfa is hexafluoroacetylacetonate dehydrate and cpo is 4-cyanopyridine-N-oxide) are pre…
Evolution of the spectrum and the metal-insulator transition in local approximations for many-electron models
A. O. Anokhin, A. V. Zarubin, V. Yu. Irkhin
In the framework of the many-electron s-d exchange model and Hubbard model, self-consistent equations are derived for the one-particle retarded Green's function in the many-electro…
Single-particle spectrum for a model of fermions interacting with two-level local excitations on a lattice: A dynamical CPA approach
A. O. Anokhin, A. V. Zarubin, V. Yu. Irkhin
The problem of motion of a single electron interacting with a periodic lattice of two-level systems is investigated within a spinless fermion model. The Green's function is calcula…
On the phonon-induced superconductivity of disordered alloys
A. O. Anokhin, M. I. Katsnelson
A model of alloy is considered which includes both quenched disorder in the electron subsystem (``alloy'' subsystem) and electron-phonon interaction. For given approximate solution…
First-principles Calculations of the Electronic Structure and Spectra of Strongly Correlated Systems: Dynamical Mean-field Theory
V. I. Anisimov, A. I. Poteryaev, M. A. Korotin +2
A recently developed dynamical mean-field theory in the iterated perturbation theory approximation was used as a basis for construction of the "first principles" calculation scheme…
