AbstractStudenikin et al.[1] recently demonstrated a significant enhancement of the fringe contrast of coherent Landau-Zener-Stückelberg (LZS) oscillations between singlet S and triplet T+ two-spin states using a modified charge detection technique called enhanced charge detection (ECD). In this paper we explain the amplitude phase reversal and confirm the magnitude of the effect is consistent with our calibrations. We also show that the enhancement cannot be explained by a T1 effect. © 2013 AIP Publishing LLC.
