Abstract
The Moore-Read Pfaffian quantum Hall state is a -wave superconductor of composite fermions. Small deviations from result in the formation of an array of vortices within this superconductor, each supporting a Majorana zero mode near its core. We consider how tunneling between these cores is reflected in the electronic response to an electric field of a nonzero wave-vector and frequency . We find a mechanism for dissipative transport at frequencies below the gap, and calculate the dependence of the dissipative conductivity. The contributions we find depend exponentially on .
