SUMMARY:Looking for Dark Energy on Earth: A New Experiment Using Atom Inter
	ferometry That Galileo Would Understand
DESCRIPTION:Featuring Martin L. Perl\, Stanford University\, SLAC\nHosted b
	y: Lawrence Sulak\nPoster: http://physics.bu.edu/posters/2011_Spring/06_Per
	l.pdf\n\nPart of the Physics Department Colloquia Series.\n\nAbstract:\n Th
	e acceleration of the expansion of the universe was discovered about a deca
	de ago by ingenious and amazing astronomical observations of supernova. Thi
	s unexpected phenomenon is called dark energy\, but very little is known ab
	out the nature of the phenomenon. Numerous astronomical observations are co
	ntinuing.\n\n We are building a unique atom interferometer laboratory exper
	iment to investigate on earth the nature of dark energy and at the same tim
	e to look for other unknown contents of the vacuum. This experiment assumes
	 that dark energy exerts a force on atoms. The experiment also assumes that
	 the density of dark energy is inhomogeneous since atom interferometry depe
	nds on a non-uniform potential.\n\n I will give a pictorial introduction to
	 the wonders of atom interferometry technology\, to the essence of this exp
	eriment and our speculative hopes.
