| Description: | [DPS Seminar] Prof. Amit Dutta (IIT Kanpur) -- Periodic steady state in a driven quantum many body system |
| Date: | Tuesday, Jan 24, 2017 |
| Time: | 10 a.m. - 11 a.m. |
| Venue: | G02, Lecture Hall Complex |
| Details: | Starting from the simple example of a Kapitza pendulum, we shall study a periodically driven closed quantum system, namely the integrable transverse Ising chain. We show that the spin chain indeed reaches a periodic steady state described by a "decohered" density matrix in the asymptotic limit of driving. In the process, I shall also provide a brief introduction to Floquet theory. |
