In this talk, we describe the theory of a Josephson resonant level and show that it provides a simple, versatile, and tractable model of a solitary Andreev level in a Josephson weak link. Within this model, we calculate the linear response to the external driving of current flowing through the junction and of charge in the junction region. The dependence of the response functions on the number of quasiparticles occupying the Andreev level is obtained. In contrast to previous studies, we take into account weak Coulomb interaction in the system and pinpoint its observable effects on the dynamic properties of Andreev levels. Finally, we show that occupied continuum states outside of the gap may give a substantial contribution to the response of the system.
