        "Strong electronic correlations far from thermal equilibrium"


        Abstract: Confined nanostructures, such as semiconductor and
        nanotube quantum dots, have become an important tool for
        investigating fundamental aspects of correlated electron systems.
        The exquisite control of the microscopic parameters in such
        devices have opened new possibilities not accessible in bulk
        systems. Perhaps the most exciting of these is the study of
        strong electronic correlations far from thermal equilibrium,
        whether under steady-state conditions or subject to real-time
        dynamics.

        The description of strong electronic correlations far from
        thermal equilibrium is one of the outstanding open questions
        in the field. Many of the theoretical approaches that have
        proven so successful in equilibrium are simply inadequate
        once the system is driven out of thermal equilibrium. Basic
        concepts, such as that of the renormalization group, are
        still lacking. In this talk I will review some of our recent
        advancements toward filling in this gap. This includes the
        development of a numerical renormalization-group approach to
        track the real-time dynamics of quantum impurities systems
        such as small quantum dots. Applications of the approach to
        quantum dissipation and to the decoherence of an impurity
        spin due to its coupling to the environment will be discussed.
