Experimental progress in strongly coupling quantum gases into quantized electromagnetic fields of quantum cavities has opened a new avenue in many-body physics — referred to commonly as many-body cavity quantum electrodynamics (QED) — where the dynamics of both quantum matter and electromagnetic fields play equally essential roles. In this talk, after a review of state of the art in many-body cavity QED I will present some of our recent theoretical works on many-body cavity QED. In particular, I will talk about emergent magnetic orders [1] and driven-dissipative supersolid [2] in many-body cavity QED systems. As an interesting application of many-body cavity QED, I will present our new proposal for a precise gravimeter based on supersolid-like states in a ring cavity [3]. Finally, if time allows, I will then talk about emergent quasicrystalline symmetries in light-induced quantum phase transitions in the framework of many-body cavity QED [4].

 Short Bio:

I did my undergraduate studies at the University of Tabriz, Azerbaijan. I then moved to Calgary, Canada for my graduate studies, where I received my Ph.D. in 2015 from the University of Calgary. After that I joined the group of Prof. Helmut Ritsch at the University of Innsbruck, Austria as a postdoctoral researcher. At the moment, I am a Lise-Meitner Research Fellow and FWF-ANR Principal Investigator at the Institute for Theoretical Physics at the University of Innsbruck, Austria.
