Unreliability of two-band model analysis of magnetoresistivities in unveiling temperature-driven Lifshitz transition

Recently, anomalies in the temperature dependences of carrier density and/or mobility derived from analysis magnetoresistivities using conventional two-band model have been used to unveil intriguing temperature-induced Lifshitz transitions various materials. For instance, two temperature-driven were inferred exist Dirac nodal-line semimetal ZrSiSe, based on Hall magnetoconductivities where second band exhibits a change type holes electrons when decreases below $T=106\phantom{\rule{0.16em}{0ex}}\mathrm{K}$ and dip is observed vs curve at $T=80\phantom{\rule{0.16em}{0ex}}\mathrm{K}$. Here, we revisit experiments ZrSiSe. We show that may be spurious because first dominates $T>80\phantom{\rule{0.16em}{0ex}}\mathrm{K}$, making obtained for unreliable. That is, care must taken interpreting these as evidence transitions. Our skepticism existence such phase ZrSiSe further supported by validation Kohler's rule magnetoresistances $T\ensuremath{\le}180\phantom{\rule{0.16em}{0ex}}\mathrm{K}$. In this paper, showcase potential issues dependence or model.
