Golden, Fulvio Parmigiani, SmB6 electron-phonon coupling constant from time- and angle-resolved photoelectron spectroscopy, Materials Cloud Archive 2021.56 (2021), doi: 10.24435/materialscloud:2b-ht.

Description

This record contains the experimental results of the first ultrafast spectroscopic investigation of the electronic properties of SmB6, proposed to realize a Kondo topological insulator. We employ a multi-temperature model to extract the electron-phonon coupling constant in the range 0.13-0.04, within the assumption of a strong coupling to the optical phonon modes in the range 10-19 meV.
