Abstract

We study the interaction effect in a three-dimensional Dirac semimetal
and find that two competing orders, charge-density-wave orders and
nematic orders, can be induced to gap the Dirac points. Applying a
magnetic field can further induce an instability towards forming these
ordered phases. The charge-density-wave phase is similar to that of
aWeyl semimetal, while the nematic phase is unique for Dirac semimetals.
Gapless zero modes are found in the vortex core formed by nematic order
parameters, indicating the topological nature of nematic phases. The
nematic phase can be observed experimentally using scanning tunneling
microscopy.
