Abstract We present a low-energy effective field theory describing the universality class of the Pfaffian quantum Hall state. To arrive at this theory, we observe that the edge theory of the Pfaffian state of bosons at v = 1 is an SU (2) 2 Kac-Moody algebra. It follows that the corresponding bulk effective field theory is an SU (2) Chem-Simons theory with coupling constant k = 2. The effective field theories for other Pfaffian states, such as the fermionic one at v = 1/2 are obtained by a flux… Expand

TLDR
In the Chern-Simons gauge theory on a manifold the unitary operators, which induce large gauge transformations shifting the nonintegrable phases of the two dinstinct Wilson-line integrals on the torus by multiples of 2..pi.., do not commute with each other unless the coefficient of the Chern -Simons term is quantized.
