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…
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…
