Dynamical description of spectral flow in N = 2 superconformal field theories Original Research Article

We show how the spectral flow between the Neveu-Schwarz and Ramond sectors of N = 2 superconformal field theories can be described in three dimensions in terms of the propagation of charged particles coupled to a Chern-Simons gauge theory. Quantum mechanical mixing between the degenerate Chern-Simons vacua interpolates between the different boundary conditions of the two sectors and so provides a dynamical picture for the GSO projection.
