Cond mat 0010440. Certain one dimensional fermi systems have an energy gap in the bulk spectrum while boundary states are described by one majorana operator per boundary point. Certain one dimensional fermi systems have an energy gap in the bulk spectrum while boundary states are described by one majorana operator per boundary point. A finite system of length l possesses two ground states with an energy difference proportional to exp l l 0 and different fermionic parities.
