Abstract:
Spectral properties of LiFeAs superconductor
are investigated within the LDA+DMFT
method. Calculated
distribution of the spectral weight in the k-space
is in good agreement with angle-resolved
photoemission (ARPES) spectra. Calculated effective electron mass enhancement factor
$m^{*}/m\approx3$ is close to the one estimated from comparison of density-functional
theory results with ARPES spectra.
Our results demonstrate that inclusion into consideration of dynamical Coulomb
correlations between
the electrons plays a key role in understanding of the spectral properties of LiFeAs.
