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…

On the absence of simultaneous reflection and transmission in integrable impurity systems
O. A. Castro-Alvaredo, A. Fring, F. Göhmann
We establish that the Yang-Baxter equations in the presence of an impurity can in general only admit solutions of simultaneous tranmission and reflection when the transmission and…
