Low energy electrodynamics and a hidden Fermi liquid in the heavy-fermion CeCoIn\(_5\)

We present time-domain THz spectroscopy of thin films of the heavy-fermion superconductor CeCoIn\(_5\). The complex optical conductivity is analyzed through a Drude model and extended Drude model analysis. Below the \(\approx\) 40 K Kondo coherence temperature, a narrow Drude-like peak forms, as the...
