Quasiparticle properties below coherence onset in YbAl3 nanostructures
Dale T. Lowder, Gage Eichman, Yuxin Wan +9
Mesoscopic transport measurements are underexplored as probes of quasiparticles and their properties in correlated metals. The mixed valence compound YbAl exhibits a single-ion…

Low energy electrodynamics and a hidden Fermi liquid in the heavy-fermion CeCoIn
L. Y. Shi, Zhenisbek Tagay, Jiahao Liang +6
We present time-domain THz spectroscopy of thin films of the heavy-fermion superconductor CeCoIn. Below the 40 K Kondo coherence temperature, a narrow Drude-like peak…

Terahertz Electrodynamics of Mixed-Valent YbAl and LuAl Thin Films
D. Barbalas, S. Chatterjee, D. G. Schlom +2
We present THz measurements of thin films of mixed-valent YbAl and its structural analogue LuAl. Combined with traditional Fourier transform infrared (FTIR) spectroscopy, t…
