  We consider the currents flowing in a solid-state interferometer under the
effect of both an Aharonov-Bohm phase and a bias potential. Expressions are
obtained for these currents, allowing for electronic or electron-boson
interactions, which may take place solely on a quantum dot placed on one of the
interferometer arms. The boson system can be out of equilibrium. The results
are used to obtain the transport current through the interferometer, and the
current circulating around it under the effect of the Aharonov-Bohm flux. The
modifications of both currents, brought about by coupling the quantum dot to an
incoherent sonic or electromagnetic source, are then analyzed. By choosing the
appropriate range of the boson source intensity and its frequency, the
magnitude of the interference-related terms of both currents can be controlled.
