Abstract
We present numerical results for the phase-periodic conductance of an Andreev interferometer and predict the existence of a voltage-induced crossover from a zero-phase minimum to a zero-phase maximum. This contrasts with a recent analysis of Stoof and Nazarov and Volkov, Allsopp, and Lambert, which predicts a vanishing amplitude of oscillation at zero temperature and voltage, respectively, and demonstrates that such behavior is nonuniversal.
