In this article we discuss conductance through a quantum dot in the fractional quantum Hall regime. We argue that in the intermediate temperature regime (F~ .~ kT ~ A) many-body coherence strongly suppresses the conductance well below the integer regime values. In particular, we find that in the u =
## Abstract Veselago medium (also called double negative material, backward medium, leftβhanded medium) is a medium with both negative isotropic dielectric permittivity and permeability. It has the effect of backward waves with negative (anomalous) refraction, in contrast to the usual forward waves
