Two-terminal conductance of a fractional quantum Hall edge

We have found solution to a model of tunneling between a multi-channel Fermi liqiud reservoir and an edge of the principal fractional quantum Hall liquid (FQHL) in the strong coupling limit. The solution explains how the chiral edge propagation makes the universal two-terminal conductance of the FQHL fractionally quantized and different from that of a 1D Tomonaga-Luttinger liquid wire, where a similar model but preserving the time reversal symmetry predicts unsuppressed free-electron conductance.
