Two-terminal conductance of a fractional quantum Hall edge

We have found a solution to a model of tunneling between a multichannel Fer mi liquid reservoir and an edge of the principal fractional quantum Hall li quid (FQHL) in the strong-coupling limit. The solution explains how the chi ral edge propagation makes the universal two-terminal conductance of the FQ HL fractionally quantized and different from that of a 1D Tomonaga-Luttinge r liquid wire, where a similar model, but preserving the time reversal symm etry, predicts unsuppressed free-electron conductance.
