Abstract
A study of self-consistently obtained solution shows that these corrections often have an effect opposite to each other, or have the same target states; which limits the overall effect. As a consequence even for large Delta/ EF the overall correction is still relatively small, and the conductance of the system does not differ much from the simple BTK model. We have thus shown the reason for robustness of BTK model, and gained a better view of what might be the cause of larger discrepancies between this simple model and experiment.
