中文摘要	coherent transport through a quantum dot embedded in one arm of a double-slit-like aharonov-bohm (ab) ring is studied using the green's function approach. we obtain experimental observations such as continuous phase shift along a single resonance peak and sharp inter-resonance phase drop. the ab oscillations of the differential conductance of the whole device are calculated by using the nonequilibrium keldysh formalism. it is shown that the oscillating conductance has a continuous bias-voltage-dependent phase shift and is asymmetric in both linear and nonlinear response regimes.
