ARPES spectral functions and Fermi surface for La(1.86)Sr(0.14)CuO(4) compared with LDA+DMFT+Sk calculations
I. A. Nekrasov, E. E. Kokorina, E. Z. Kuchinskii +4
Slightly underdoped high-Tc system La(1.86)Sr(0.14)CuO(4) (LSCO) is studied by means of high energy high resolution angular resolved photoemission spectroscopy (ARPES) and combined…
Two-dimensional Anderson-Hubbard model in DMFT+Sigma approximation
E. Z. Kuchinskii, N. A. Kuleeva, I. A. Nekrasov +1
Density of states, dynamic (optical) conductivity and phase diagram of paramagnetic two-dimensional Anderson-Hubbard model with strong correlations and disorder are analyzed within…
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…
Multiple Bands - A Key to High - Temperature Superconductivity in Iron Arsenides?
E. Z. Kuchinskii, M. V. Sadovskii
In the framework of four-band model of superconductivity in iron arsenides proposed by Barzykin and Gor'kov we analyze the gap ratios on hole - like and electron - like Fermi - sur…
