A major effort in this direction has been devoted to using classical light in the form of Floquet drives to manipulate and induce states with non-trivial topology. A different route can be achieved with cavity photons. In this talk, I will discuss a prototypical model for topological phase transition, the one-dimensional Su-Schrieffer-Heeger (SSH) model, coupled to a single mode cavity [1]. I will demonstrate that quantum light can affect the topological properties of the system, including the finite-length energy spectrum hosting edge modes and the topological phase diagram. In particular, I will show that depending on the lattice geometry and the strength of light-matter coupling one can either turn a trivial phase into a topological one or vice versa using quantum cavity fields. Furthermore, the polariton spectrum of the coupled electron-photon system contains signatures of the topological phase transition in the SSH model.<\/p>\n<hr>\n<p><strong>References:<\/strong><\/p>\n<p>[1] Olesia Dmytruk and Marco Schir\u00f3, Controlling topological phases of matter with quantum light,&nbsp;<a href=\"https:\/\/arxiv.org\/abs\/2204.05922\">arXiv:2204.05922<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Olesia Dmytruk, from the CNRS, Coll\u00e8ge de France, PSL Research University, Paris Date: November 22, 2022, 12:00h Location:&nbsp;Instituto de Ciencias de Materiales de Madrid (ICMM-CSIC), Sal\u00f3n de Actos Abstract: Controlling the topological properties of quantum matter is a major goal of condensed matter physics.
