Merging diabolical points of a superconducting circuit
We present the first theoretical study of the 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.Comment: 11 pages, 6 figure
