Comment on Unusual violation of the Wiedemann-Franz law at ultralow temperatures in topological compensated semimetals
arXiv:2503.13968
Abstract
Recently, Wang et al. [1] reported on an unusual violation of Wiedemann-Franz law in three semimetals. We compare their observations to our observations in a variety of systems, where the apparent WF law violations in the same temperature range arise as a consequence of electron-phonon decoupling. Given the empirical similarity of their data with these cases, the most plausible explanation for the reported violation is an experimental artefact.
