Neutral modes measurements in the fractional quantum Hall effect regime

Merav Dolev, Department of Condensed Matter Physics
Weizmann Institute

The discovery of neutral (energy carrying) edge modes in the
fractional quantum Hall effect regime (Bid et. al. Nature, 2010)
opened a new and fascinating field of research. In this talk, I
will discuss fractional quantum Hall states in which an upstream
neutral mode had been recently observed. In particular, I will
focus on fractional quantum Hall states in the second Landau level
(ν=8/3, ν=5/2 and ν=7/3), which may support non abelian
quasiparticles. Since non abelian quasiparticles are expected to
carry a fractional charge and a unique form of a chiral neutral
edge mode, charge measurement accompanied with neutral mode 
detection measurement may provide an indication for possible non
abelian candidates.
