Topological crystalline superconductivity and second-order topological superconductivity in nodal-loop materials
Hassan Shapourian, Yuxuan Wang, Shinsei Ryu
We study the intrinsic fully-gapped odd-parity superconducting order in doped nodal-loop materials with a torus-shaped Fermi surface. We show that the mirror symmetry, which protec…

Many-body topological invariants for fermionic short-range entangled topological phases protected by antiunitary symmetries
Ken Shiozaki, Hassan Shapourian, Kiyonori Gomi +1
We present a fully many-body formulation of topological invariants for various topological phases of fermions protected by antiunitary symmetry, which does not refer to single part…
