Introduction
Three magnetotransport signatures in ZrTe₅ flakes change near a common characteristic temperature. That temperature shifts with thickness, and the authors discuss a temperature-induced topological transition as an explanation.
A closer reading
A common temperature scale across three observables is more informative than one kink. Their agreement constrains a transition scenario, but is distinct from a direct determination of band topology.
