Résumé : When spatial boundaries are inserted, supersymmetry (SUSY) can be broken. We have shown that in an N=2 supersymmetric theory, all local boundary conditions allowed by self-adjointness of the Hamiltonian break N=2 SUSY, while only a few of these boundary conditions preserve N=1 SUSY. We have also shown that for a subset of the boundary conditions compatible with N=1 SUSY, there exist fermionic ground states which are localized near the boundary. We also show that only very few nonlocal boundary conditions like periodic boundary conditions preserve full N=2 supersymmetry, but none of them exhibits edge states.
