The quantum hall effect in quasi-1D conductors

The theory and experiments showing Quantum Hall effect in the quasi-one-dimensional conductors of the Bechgaard salts family are briefly reviewed. The sign reversals observed under some experimental conditions are explained within the framework of the Quantized Nesting Model. The sequence of reversals is driven by slight modifications of the geometry of the Fermi surface. It is explained why only even phases can have sign reversals and why negative phases are less stable than positive ones.
