Scattering amplitudes in non-Fermi liquid systems
A. Koutouza, F. Lesage, H. Saleur
By a mix of form-factors and analyticity techniques, we determine some fundamental scattering amplitudes in non-Fermi liquid systems. These include the reflection and transmission…

How Irrelevant Operators affect the Determination of Fractional Charge
A. Koutouza, H. Saleur, B. Trauzettel
We show that the inclusion of irrelevant terms in the Hamiltonian describing tunneling between edge states in the fractional quantum Hall effect can lead to a variety of non pertur…
