Electronic structure of CeIr3 superconductor: DMFT studies

We present the band structure of CeIr$_3$ superconductor calculated within dynamical mean field theory (DMFT). Standard GGA and GGA+U methods fail to reproduce experimental electronic specific heat coefficient $\gamma_{\rm expt.}$ due underestimated density states at Fermi level $N(E_F)$ followed by an overestimated strength electron-phonon coupling (EPC) as a renormalization expt.}$. The DMFT study shows strong hybridization $4f$ Ce with $5d$-states Ir, which leads larger giving correct moderate EPC in agreement data.
