Nonequilibrium Quantum Matter Coupled To Quantum Light

ended

Light-matter interaction is a fundamental physical phenomena that can be used to probe properties of the materials by spectroscopic measurements. However, experimental progress in manipulating light and matter at quantum level opens the possibility of using electromagnetic radiation to control and design material properties, by embedding them into high-finesse optical resonators. Cavity photons could be used to enhance or induce superconductivity, topological properties in electronic materials and to create new quantum phases characterised by new hybrid mixed light-matter quasiparticles. The aim of this project is to use properties of light to probe and engineer new phases of matter. In this project, I will study properties of mesoscopic capacitors and strongly correlated electronic materials coupled to (driven) electromagnetic field of the cavity. In particular, I will focus on creating strongly coupled electron-photon systems in mesoscopic quantum circuits coupled to resonators, on characterising the properties of strongly correlated electronic systems driven by cavity photons and the new phases of matter that can emerge in this context, due to the interplay between strong electron-electron interactions and light-matter coupling. This will require a development of new theoretical tools to study non-equilibrium dissipative fermion-boson systems. Moreover, I will study how one can generate new topological phases of matter with light in the setups based on a strongly correlated electronic material coupled to a (driven) cavity. This projects will be at the interface of mesoscopic physics, strongly correlated electrons and quantum optics, building on my past research experience and the expertise of the host group.
