Query: Dirac surface states in magnonic analogs of topological crystalline
  insulators   We propose magnonic analogs of topological crystalline insulators which
possess Dirac surface states protected by the combined symmetry of
time-reversal and half translation. Constructing models of the topological
magnon systems, we demonstrate that the energy current flows through the
systems in response to an electric field, owing to the Dirac surface states
with the spin-momentum locking. We also propose a realization of the magnonic
analogs of topological crystalline insulators in a magnetic compound CrI$_{3}$
with a monoclinic structure.
