Mark Rudner (Harvard University):
"Topological Transitions in Driven Quantum Systems"

The discovery of the quantized Hall effects opened a new chapter in our
understanding of quantum mechanics. The theoretical explanation of these
effects, which is based on the mathematical framework of topology, revealed
new mechanisms through which extremely robust quantization phenomena could
arise in large, and rather messy systems. Building on these ideas, whole
new classes of materials with startling properties have recently been
predicted and identified experimentally. Now, as we progress into the 21st
century, a variety of new experimental tools offer unprecedented levels of
control over solid-state, atomic, and optical systems. In this talk, I will
discuss new types of topologically-protected robust quantum behavior which
arise in periodically-driven quantum systems. I will begin by reviewing
various types quantization phenomena, and will provide a introduction to
the connection between topology and quantum systems. Then I will show how
these concepts can be extended and applied in new ways to driven systems,
drawing on discrete time quantum walks as a prototypical example.
