The three-dimensional topological Dirac semimetal Na${}_3$Bi: the ground state phase

Xiyue Cheng, Ronghan Li, Xing-Qiu Chen +2

By means of first-principles calculations, we found that the early characterized three-dimensional topological bulk Dirac semimetal of the $P$6${}_3$/$mmc$ Na${}_3$Bi is dynamically un…
