		"Geometrical frustration" refers to a phenomenon in which magnets, or other materials, are "frustrated" when they are forced to settle into a single state.
		For example, Ramirez recently found several of the hallmarks of geometrical frustration in a material that undergoes negative thermal expansion, meaning that it expands (rather than shrinks) as it is cooled.
		While at Bell Labs, Ramirez pioneered the field of "geometrical frustration" in magnetism.

		In particular, geometrically frustrated systems (having as a basic building block triangles of antiferromagnetic bonds) have been the object of extensive theoretical studies.
		Recently, more and more experimental realizations of such geometrically frustrated systems have been achieved.
		Since the effects of frustration are more pronounced in lower dimensions, the best candidates for disorder-free glassiness are two dimensional antiferromagnets on triangular or kagomé lattices.
