fractional quantum Hall effect

[¦frak·shən·əl ′kwän·təm ′hȯl i‚fekt]
(electronics)
The version of the quantum Hall effect in which the Hall resistance becomes precisely equal to h /(p / q) e 2, where h is Planck's constant, e is the electronic charge, q is an odd integer, and p is an integer not divisible by q.

They therefore named the new phenomenon the fractional quantum Hall effect.
This allows situations where, similar to the fractional quantum Hall effect, the charge fractionalization leads to conductance with quantized fractional numbers of the von Klitzing conductance e^2/h.
