The Fermi surface and the role of electronic correlations in Sm${}_{2-x}$Ce${}_x$CuO${}_4$

M. M. Korshunov, E. V. Zakharova, I. A. Nekrasov +2

Using LDA+GTB (local density approximation+generalized tight-binding) hybrid scheme we investigate the band structure of the electron-doped high-$T_c$ material Sm${}_{2-x}$Ce${}_x$Cu…
