This study investigates the boundary supersymmetry of one-dimensional fermionic phases beyond SPT phases, calculating the number of protected boundary supercharges based on bulk phase invariants. Using the connection between Majorana edge modes and real supercharges, the researchers were able to derive this information.
It has recently been demonstrated that protected supersymmetry emerges on the boundaries of one-dimensional intrinsically fermionic symmetry protected trivial (SPT) phases. Here we investigate the boundary supersymmetry of one-dimensional fermionic phases beyond SPT phases. Using the connection between Majorana edge modes and real supercharges, we compute, in terms of the bulk phase invariants, the number of protected boundary supercharges.
