Dominance of many-body effects over one-electron mechanism for band structure doping dependence in NdCeCuO: LDA+GTB approach
M. M. Korshunov, V. A. Gavrichkov, S. G. Ovchinnikov +3
In the present work we report the band structure calculations for the high temperature superconductor NdCeCuO in the regime of strong electronic correlations within…
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…
Prediction of the in-Gap States Above the Top of the Valence Band in the Undoped Insulating Cuprates due to Spin-Polaron Effect
S. G. Ovchinnikov, A. A. Borisov, V. A. Gavrichkov +1
In the framework of the generalized tight binding method we have calculated the quasiparticle band structure and the spectral functions of the undoped cuprates like , $…
