Anomalous tunneling conductances of a spin singlet ν=2/3 edge states: Interplay of Zeeman splitting and Long Range Coulomb Interaction

H. C. Lee

The point contact tunneling conductance between edges of the spin singlet $\nu =2/3,\hat{K}=(3/3/0)$ quantum Hall states is studied both in the quasiparticle tunneling picture and in…
