One-dimensionality signature in optical conductivity of heavy-fermion

BG Jang, KR O'Neal, C Lane, TU Böhm, N Sirica… - Physical Review B, 2023 - APS
In low dimensions, the combined effects of interactions and quantum fluctuations can lead to
dramatically new physics distinct from that existing in higher dimensions. Here, we …

Effect of Cd- and Sn-doping in on the hybridization gap and -electron amplitude studied with infrared spectroscopy

M Lee, YS Seo, S Roh, S Lee, J Kim, T Park, J Hwang - Physical Review B, 2024 - APS
We investigated hole (Cd)-and electron (Sn)-doped CeCoIn 5 [CeCo (In 1− x T x) 5 (T= Cd
or Sn)] using infrared spectroscopy. Doping-dependent hybridization-gap distribution …
