Interplay of electron-phonon interaction and strong correlations: DMFT+Σstudy
E. Z. Kuchinskii, I. A. Nekrasov, M. V. Sadovskii
We perform investigation of Hubbard model with interaction between strongly correlated conducting electrons on a lattice with Debye phonons. To solve the problem generalized dynami…
Electronic structure of Pr_{2-x}Ce_xCuO_4 studied via ARPES and LDA+DMFT+Σ_k
I. A. Nekrasov, N. S. Pavlov, E. Z. Kuchinskii +10
The electron-doped Pr(2-x)Ce(x)CuO(4) (PCCO) compound in the pseudogap regime (x~0.15) was investigated using angle-resolved photoemission spectroscopy (ARPES) and the generalized…
Reconstruction of the Fermi surface in the pseudogap state of cuprates
E. Z. Kuchinskii, M. V. Sadovskii
Reconstruction of the Fermi surface of high-temperature superconducting cuprates in the pseudogap state is analyzed within nearly exactly solvable model of the pseudogap state, ind…
Origin of "hot-spots" in the pseudogap regime of Nd(1.85)Ce(0.15)CuO(4): LDA+DMFT+Sigma_k study
E. E. Kokorina, E. Z. Kuchinskii, I. A. Nekrasov +5
Material specific electronic band structure of the electron-doped high-Tc cuprate Nd(1.85)Ce(0.15)CuO(4) (NCCO) is calculated within the pseudo gap regime, using the recently devel…
Optical Sum Rule in Strongly Correlated Systems
E. Z. Kuchinskii, N. A. Kuleeva, I. A. Nekrasov +1
We discuss the problem of a possible "violation" of the optical sum rule in the normal (non superconducting) state of strongly correlated electronic systems, using our recently pro…
Comparative study of electron and hole doped High-Tc compounds in pseudogap regime: LDA+DMFT+Sk approach
I. A. Nekrasov, E. E. Kokorina, E. Z. Kuchinskii +2
Pseudogap regime for the prototype high-Tc compounds hole doped Bi2Sr2CaCu2O8-x (Bi2212) and electron doped Nd2-xCexCuO4 (NCCO) is described by means of novel generalized LDA+DMFT+…
