Rational sequences for the conductance in quantum wires from affine Toda field theories
Olalla A. Castro-Alvaredo, Andreas Fring
We analyse the expression for the conductance of a quantum wire which is decribed by an integrable quantum field theory. In the high temperature regime we derive a simple formula f…
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…
Relativistic treatment of harmonics from impurity systems in quantum wires
O. A. Castro-Alvaredo, A. Fring, C. Figueira de Morisson Faria
Within a one particle approximation of the Dirac equation we investigate a defect system in a quantum wire. We demonstrate that by minimally coupling a laser field of frequency ome…
From integrability to conductance, impurity systems
Olalla Castro-Alvaredo, Andreas Fring
We compute the DC conductance with two different methods, which both exploit the integrability of the theories under consideration. On one hand we determine the conductance through…
Finite temperature correlation functions from form factors
O. A. Castro-Alvaredo, A. Fring
We investigate proposals of how the form factor approach to compute correlation functions at zero temperature can be extended to finite temperature. For the two-point correlation f…
