The electronic structures of the heavy-fermion superconductor CeRh2As2 with the local inversion symmetry breaking and the reference material LaRh2As2 have been investigated by using experimental optical conductivity (σ1(ω)) spectra and first-principal DFT calculations. In the low-temperature σ1(ω) spectra of CeRh2As2, a 4f–conduction electron hybridization and heavy quasiparticles are clearly indicated by a mid-infrared peak and a narrow Drude peak. In LaRh2As2, these features are absent in the… Expand
