Conductance from Non-perturbative Methods I
Olalla A. Castro-Alvaredo, Andreas Fring
We investigate different methods to compute the DC conductance in a quantum wire doped with some impuritied by exploiting the integrability of the theories under consideration. As…

Conductance from Non-perturbative Methods II
Olalla A. Castro-Alvaredo, Andreas Fring
This talk provides a natural continuation of the talk presented by Andreas Fring in this conference. Part I was focused on explaining how the DC conductance for a free Fermion theo…

Unstable particles versus resonances in impurity systems, conductance in quantum wires
O. A. Castro-Alvaredo, A. Fring
We compute the DC conductance for a homogeneous sine-Gordon model and an impurity system of Luttinger liquid type by means of the thermodynamic Bethe ansatz and standard potential…
