DESCRIPTION:Speaker: Yuto Ashida\nhosted by Johannes Fink\nAbstract: Strong
  coupling between matter and quantized electromagnetic modes may offer yet
  another approach of controlling equilibrium phases or dynamics of quantum
  many-body systems. Recent developments have realized such strong light-ma
 tter interaction in genuinely nonperturbative regimes\, where conventional
  theoretical methods often fail. I will talk about how one can analyze str
 ongly coupled quantum light-matter systems at arbitrary interaction streng
 ths on the basis of an asymptotically disentangling unitary transformation
  [1\,2]. I discuss its application to construction of tight-binding Hamilt
 onians\, dynamics of bound states in the continuum\, and revisiting dissip
 ative quantum phase transition in resistively shunted Josephson junctions
