Merging diabolical points of a superconducting circuit    [PDF]

Amélie Monjou, Raphaël Leone

We present a first theoretical study of a merging of diabolical points in the context of superconducting circuits. We begin by studying an analytically solvable four-level model which may serve as theoretical pattern for such a phenomenon. Then, we apply it to a circuit named Cooper pairs pump, whose diabolical points are already known.
