Query: Topological superconductivity in Dirac semimetals   Dirac semimetals host bulk band-touching Dirac points and a surface Fermi
loop. We develop a theory of superconducting Dirac semimetals. Establishing a
relation between the Dirac points and the surface Fermi loop, we clarify how
the nontrivial topology of Dirac semimetals affects their superconducting
state. We note that the unique orbital texture of Dirac points and a structural
phase transition of the crystal favor symmetry-protected topological
superconductivity with a quartet of surface Majorana fermions. We suggest
possible application of our theory to recently discovered superconducting
states in Cd$_3$As$_2$.
