Phys. Rev. Lett. 86, 143–146 (2001)Plateau Behavior in the Chiral Luttinger Liquid ExponentReceived 16 June 1999; published in the issue dated 1 January 2001 The current-voltage power law exponent, α, for electron tunneling into chiral Luttinger liquids at the fractional quantum Hall edge is found to exhibit a plateaulike structure at α close to 3 as the filling factor, ν, is varied. The presence of a plateau near α = 3 strongly suggests a fundamental connection between α and the structure of the underlying quantum ground states associated with the robust incompressible ν = 1/3 Hall fluid. However, the position in the inverse filling factor where the plateau occurs can vary between samples and appears shifted to values higher than expected from theory. © 2001 The American Physical Society URL:
