SUMMARY:Suppression of the critical temperature for superfluidity near the 
	Mott transition: validating a quantum simulator 
DESCRIPTION:Featuring Lode Pollet\, Harvard University\n\nPart of the Conde
	nsed Matter Theory Seminar Series.\n\nAbstract: Ultra-cold atoms in an opti
	cal lattice offer an unique opportunity to study prototypical models of con
	densed matter physics\, serving as quantum simulators. Before they can be t
	rusted for unknown models\, they first need to be validated against known m
	odels. This benchmarking is the topic of the present study\, where we compa
	re the phase diagram of the Bose-Hubbard model obtained in  experiment (gro
	up of I. Bloch) and numerics. We present the first full ab-initio compariso
	n  for strongly interacting Bose gases on a lattice for large systems (up t
	o 300\,000 atoms). The comparison has enabled us to perform thermometry for
	 the interacting quantum gas to experimentally determine the finite tempera
	ture phase diagram for bosonic superfluids in an optical lattice\, and chec
	k the validity of the conservation of entropy assumption. Our results revea
	l a downshift of the critical temperature as the transition to the Mott ins
	ulator is approached.\n\nRef: S. Trotzky et al.\, arXiv:0905.4882
