 abstract = {We study transport across a point contact separating two line junctions
in a nu = 5/2 quantum Hall system. We analyze the effect of inter-edge
Coulomb interactions between the chiral bosonic edge modes of the
half-filled Landau level (assuming a Pfaffian wave function for the
half-filled state) and of the two fully filled Landau levels. In the
presence of inter-edge Coulomb interactions between all the six edges
participating in the line junction, we show that the stable fixed point
corresponds to a point contact that is neither fully opaque nor fully
transparent. Remarkably, this fixed point represents a situation where
the half-filled level is fully transmitting, while the two filled levels
are completely backscattered; hence the fixed point Hall conductance is
given by G(H) = 1/2e(2)/h. We predict the non-universal temperature
power laws by which the system approaches the stable fixed point from
the two unstable fixed points corresponding to the fully connected case
(G(H) = 5/2e(2)/h) and the fully disconnected case (G(H) = 0). Copyright
