摘要：
Using a realistic model of an Aharonov-Bohm ring with a quantum dot in one arm and a control gate in the other, we demonstrate phase persistence in the Fano and Aharonov-Bohm effects as has been observed in experiments. The Fano effects in the conductance is examined by changing the states in the Aharonov-Bohm ring by the control gate.
