There has been a great deal of interest over the last two decades on the fractional quantum Hall effect, a novel quantum many-body liquid state of strongly correlated two-dimensional electronic systems in a strong perpendicular magnetic field. The most pronounced fractional quantum Hall states occur

In a previous work [O. Ciftja, Physica B 404 (2009) 227] we reported the exact calculation of energies for the fractional quantum Hall Laughlin state at filling factor n ΒΌ 1 3 for systems with up to N ΒΌ 4 electrons in a disk geometry. The purpose of this brief extension of the earlier work is to rep
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 =
