Terahertz conductivity of heavy-fermion systems from time-resolved spectroscopy
Terahertz conductivity of heavy-fermion systems from time-resolved spectroscopy
The Drude model describes the free-electron conduction in simple metals, governed by the freedom that the mobile electrons have within the material. In strongly correlated systems, however, a significant deviation of the optical conductivity from the simple metallic Drude behavior is observed. Here, we investigate the optical conductivity of the …
