SUMMARY:Ultracold fermions and bosons in Toronto
DESCRIPTION:Featuring Joseph Thywissen\, University of Toronto\n\nPart of t
	he Condensed Matter Theory Seminar Series.\n\nAbstract: I will give a progr
	ess report of two ultra-cold atom experiments underway at the University of
	 Toronto. The first is a double well boson experiment\, in which a Bose con
	densate of 87Rb is split by a tunnelling barrier. We observe matter wave in
	terference from the split condensate when released\, from which the relativ
	e phase of the condensates can be determined. Relative atom number\, the co
	njugate variable to relative phase\, can also be observed directly. We demo
	nstrate counting at the atom shot noise level. The second experiment presen
	ted will be a two-dimensional optical lattice for ultra-cold fermionic 40K.
	 We are developing site-resolved imaging of atoms in the lattice\, in order
	 to probe ordering in the planar lattice. Applications to quantum simulatio
	n of fermion lattice problems will be discussed.
