摘要
Using conformal field theory and integrability ideas, we give a full characterization of the low-temperature regime of the anisotropic interacting resonant level model. We determine the low-temperature corrections to the linear conductance exactly up to the sixth order. We show that the structure displays "Coulomb deblocking" at resonance, i.e., a strong impurity-wire capacitive coupling enhances the conductance at low temperature.
