I and Frank worked on it, was accepted for publication in Physical Review B in the third week after submitted. This is a new score in short-time reviewing process perhaps because we paid it off from working on it for almost a year!
If you are working on the critical current noise in superconducting materials or in general you deal with superconducting qubits or SQUIDS, reading this paper is highly recommended.
You will find in it a good analytical approach to understand the complicated physics of a magnetic impurity inside a Josephson junction. With the consistency it provides with the Wilson type renormalization group method so far was used in the Kondo community, it equips us to study the critical current noise in a tunnel junction in the presence of a few free Oxygen molecules inside the tunnel junction oxide layer.
