Higher-order topological superconductivity of spin-polarized fermions
Junyeong Ahn, Bohm-Jung Yang
Abstract
The authors propose centrosymmetric ferromagnetic semimetals as promising platforms for higher-order topological superconductivity in any dimensions. This work is based on a generalization of the Fu-Kane-Sato parity formula for conventional topological superconductors to parity formulas for inversion-symmetric higher-order topological superconductors.
