Nodal quasiparticle dynamics in the heavy fermion superconductor CeCoIn 5 revealed by precision microwave spectroscopy

Although heavy fermion and cuprate superconductors are both unconventional superconductors, their composition and structure differ markedly. Yet, microwave spectra collected by Truncik et al. reveal a similarity in the charge dynamics of the heavy fermion superconductor CeCoIn5 and the cuprates.
