Spectroscopic Evidence of the Aharonov-Casher Effect in a Cooper Pair Box
2016
Physical Review Letters
We have observed the effect of the Aharonov-Casher (AC) interference on the spectrum of a superconducting system containing a symmetric Cooper pair box (CPB) and a large inductance. By varying the charge n_g induced on the CPB island, we observed oscillations of the device spectrum with the period Δ n_g=2e. These oscillations are attributed to the charge-controlled AC interference between the fluxon tunneling processes in the CPB Josephson junctions. Total suppression of the tunneling (complete
