Spin-charge separation in Quantum Hall Liquids
arXiv:cond-mat/9710226 · doi:10.1103/PhysRevB.56.R15529
Abstract
We have investigated chiral edges of a quantum Hall(QH) liquid at filling factor ν=2. We find that spin and charge separate in the presence of the long-range Coulomb interaction, and the tunneling density of states(DOS) is given by D(Ï)\sim [-1/\lnÏ]^{1/2}. The measurement of the temperature and voltage dependences of the tunneling current should reveal the presence spin-charge separation.
