"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.
