Quantum Lunch: Periodically driven impurity in the XX quantum spin chain

Speaker: Giuseppe Genovese from Universität Zurich.

Title:
Periodically driven impurity in the XX quantum spin chain

Abstract:
Consider a XX quantum spin chain with a periodic forcing, acting only on one site.
Some interesting features of this system will be discussed, both on the mathematical and physical viewpoint.

In particular we will show that, if the driving frequency is sufficiently high, the state of the system becomes asymptotically a periodic function of time. A joint work with L. Corsi.
