Query: Symmetry-protected line nodes and Majorana flat bands in nodal
  crystalline superconductors   Line nodes in the superconducting gap are known to be a source of Majorana
flat bands (MFBs) in time-reversal-invariant superconductors (SCs). Here, we
extend this relation to all symmetry-protected line nodes where an additional
constraint arising from a symmetry of the crystal destabilizes or hides the
existence of MFBs. By establishing a one-to-one correspondence between group
theoretical and topological classifications, we are able to classify the
possible line-node-induced MFBs, including cases with (magnetic) non-symmorphic
space groups. Our theoretical analysis reveals a new type of MFB, i.e., MFBs in
antiferromagnetic SCs.
