Title: Spectral flow dissipation in superconducting point contacts.

Journal Article · · Europhy. Lett.

We find that multiple Andreev reflections mediating the transport in superconducting point contacts are strongly affected by a small amount of impurities in the area of the contact. We also argue that the model based on Zener transitions within independent conducting channels is not suitable for kinetic processes in multichannel contacts.
