Are the surface Fermi arcs in Dirac semimetals topologically protected?
Motivated by recent experiments probing anomalous surface states of Dirac semimetals (DSMs) Na(3)Bi and Cd(3)As(2), we raise the question posed in the title. We find that, in marked contrast to Weyl semimetals, the gapless surface states of DSMs are not topologically protected in general, except on...
