"We compute the effect of Landau-level mixing on the effective two-body and three-body pseudopotentials for electrons in the lowest and second Landau levels," scientists in the United States report.
"We find that the resulting effective three-body interaction is attractive in the lowest relative angular momentum channel. The renormalization of the two-body pseudopotentials also shows interesting structure," wrote W. Bishara and colleagues, California Institute of Technology.
The researchers concluded: "We comment on the implications for the v = 5/2 fractional quantum Hall state."
Bishara and colleagues published their study in Physical Review B ...
