Nonequilibrium steady states are explicitly constructed for a noninteracting
electron model of an Aharonov-Bohm (AB) ring with a quantum dot (QD) with the
aid of asymptotic fields. The Fano line shapes and AB oscillations are shown to
strongly depend on the bias voltage. Current fluctuations are studied as well.
