Crystalline topological Dirac semimetal phase in rutile structure ${\beta }^{\prime }$-PtO${}_2$

Rokyeon Kim, Bohm-Jung Yang, Choong H. Kim

Based on first-principles calculations and symmetry analysis, we propose that a transition metal rutile oxide, in particular ${\beta }^{\prime }$-PtO${}_2$, can host a three-dimensional topological…
