Abstract: | Supersymmetry generators are constructed from the physical operators in a quantum field theory of interacting Bose and Fermi fields where a soliton is present. These supersymmetry generators obey a standard supersymmetry algebra with a central charge and can be used to give an algebraic proof of charge fractionalization of the soliton ground state. |
