## Distinguishing the gapped and Weyl semimetal scenario in $\mathrm{Zr}{\mathrm{Te}}_{5}$: Insights from an effective two-band model

### In: Physical Review B, 2020, vol. 102, no. 12, p. 125201

Here we study the static and dynamic transport properties of a low-energy two-band model proposed previously in Martino et al. [PRL 122, 217402 (2019)], with an anisotropic in-plane linear momentum dependence and a parabolic out-of-plane dispersion. The model is extended to include a negative band gap, which leads to the emergence of a Weyl semimetal (WSM) state, as opposed to the gapped... More
