Pseudogaps: Introducing the Length Scale into DMFT
E. Z. Kuchinskii, I. A. Nekrasov, M. V. Sadovskii
Pseudogap physics in strongly correlated systems is essentially scale dependent. We generalize the dynamical mean field theory (DMFT) by including into the DMFT equations dependenc…
"Destruction" of the fermi surface due to pseudogap fluctuations in strongly correlated systems
E. Z. Kuchinskii, I. A. Nekrasov, M. V. Sadovskii
We generalize the dynamical - mean field theory (DMFT) by including into the DMFT equations dependence on correlation length of pseudogap fluctuations via additional (momentum depe…
A new hybrid LDA and Generalized Tight-Binding method for the electronic structure calculations of strongly correlated electron systems
V. A. Gavrichkov, M. M. Korshunov, S. G. Ovchinnikov +3
A novel hybrid scheme is proposed. The {\it ab initio} LDA calculation is used to construct the Wannier functions and obtain single electron and Coulomb parameters of the multiband…
The role of transition metal impurities and oxygen vacancies in the formation of ferromagnetism in Co-doped TiO2
V. I. Anisimov, M. A. Korotin, I. A. Nekrasov +4
We have investigated the role of transition metal impurities and oxygen vacancies in the formation of ferromagnetism in Co-doped TiO2 using LSDA+U approach which takes into account…
Comparative study of correlation effects in CaVO3 and SrVO3
I. A. Nekrasov, G. Keller, D. E. Kondakov +5
We present parameter-free LDA+DMFT (local density approximation + dynamical mean field theory) results for the many-body spectra of cubic SrVO3 and orthorhombic CaVO3. Both systems…
