space-time coordinates and the details of Oles' talk. The idea is that one can compute, with high accuracy, the spectral properties of disordered (containing some randomness) systems using free probability and random matrix theories. The Floquet systems will serve as a concrete example.

The seminar will be held in the *Duboc room 4-331* Please see the details of Oles’ talk below. *Title:* Stability of Disordered Floquet Topological Phases *Abstract:* In modern experiments, high-frequency periodic fields are used to create Floquet topological phases of matter. Taking into account the complex nature of finite-frequency disorder contribution to the Floquet Hamiltonian, one may wonder about the stability of these systems against local disorder. We leverage modern free probability theory and ideas in random matrices to predict the fate of finite frequency Floquet topological phase in the presence of such disorder. We confirm, depending on disorder strength, the existence of gapped topological and gapless trivial phases, as well as a transition between them at a critical disorder strength. Our method can be applied to a variety of Floquet models and shows a good agreement with numerical simulations. arXiv: 1803.08519 <https://arxiv.org/abs/1803.08519> Date: Friday, April 13, 2018 Time: 12:00pm noon Room: Duboc room 4-331 Host: Brian Skinner Thank you, Lesley Lesley Keaney Administrative Assistant Condensed Matter Theory Group MIT Department of Physics Room 6C-339 Cambridge, MA 02139 617.253.4878 (phone); 617.253.2562 (fax) _______________________________________________ CMT_seminar mailing list CMT_seminar(a)mit.edu http://mailman.mit.edu/mailman/listinfo/cmt_seminar -- Ramis _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip
