Theoretical investigation finds that edge modes in Fibonacci quasicrystals form Fibonacci-Andreev bound states that control and can dominate the Josephson current via phason angle tuning.
This effect explains the values In/Ic > 1 for finite n, which do not mean that the current increases over the maximum current that flows across the junction
