摘要：
We have extended the circuit theory of Andreev conductance [Phys. Rev. Lett. 73, 1420 (1994)] to diffusive superconducting hybrid structures that contain an Aharonov-Bohm ring. The electrostatic potential distribution in the system is predicted to be flux dependent with a period of the superconducting flux quantum Phi(0) = h/2e. When at least one tunnel barrier is present, the conductance of the system oscillates with the same period.
