                              "Quantum impurities out of equilibrium"

        Abstract: We develop an exact nonperturbative framework to compute
        steady-state properties of strongly correlated quantum impurities 
subject to
        a finite bias. We show that the steady-state physics of these systems 
is
        captured by nonequilibrium scattering eigenstates which satisfy an
        appropriate Lippman-Schwinger equation. Introducing a generalization 
of the
        equilibrium Bethe Ansatz -the Scattering Bethe Ansatz - we explicitly
        construct the scattering eigenstates for the Interacting Resonance 
Level and
        Kondo Model and derive exact, nonperturbative results for their 
steady-state
        properties.
