SUMMARY:Quantum Many Body Physics with Strongly Interacting Light-Matter Sy
	stems
DESCRIPTION:Featuring Dr. Marco Schiro' \, Princeton University\nHosted by:
	 Luca D'Alessio\n\nPart of the Condensed Matter Theory Seminar Series.\n\nA
	bstract:\nIn the physics of strongly correlated quantum systems the electro
	magnetic\nradiation has traditionally assumed the role of a spectroscopic p
	robe and\nthus treated as a classical field.\nIn recent years an increasing
	 control over light-matter interactions at\nthe genuine quantum level has b
	een achieved due to experimental\ndevelopments in quantum optics  and quant
	um electronics . This has brought\nforth a novel class of many body systems
	 where elementary excitations are\nmade by single quanta of light and matte
	r. These hybrid setups are\ncurrently attracting a great experimental and t
	heoretical interest\, for\nthe unique features they offer to explore quantu
	m many body physics in\nnovel far from equilibrium regimes.  Motivated by t
	he experimental effort\ncurrently ongoing at Princeton\, to realize these c
	orrelated systems of\nphotons and atoms using superconducting circuits\, in
	 this talk I will\ndiscuss the physics of large arrays of microwave resonat
	ors coupled to\nsuperconducting qubits via the elementary Rabi non-linearit
	y. I will argue\nthat the very nature of photon field and its interaction w
	ith matter-like\nexcitations allows to stabilize finite-density quantum pha
	ses of\ncorrelated photons out of the vacuum. I will discuss the properties
	 of\nthese phases and the quantum phase transition occurring between them a
	nd\nhighlight the differences with the physics of interacting massive quant
	um\nparticles.
