SUMMARY:Heavy Fermion Superconductors:  the little spin that could
DESCRIPTION:Featuring Piers Coleman\, Rutgers University\nHosted by: Claudi
	o Chamon\n\nPart of the Biophysics/Condensed Matter Seminar Series.\n\nAbst
	ract:  Three years after the discovery of superfluid He-3 was discovered\, 
	Physicists observed heavy fermion superconductivity\, yet the open mind-set
	 required to embrace these results as a discovery\, rather than a materials
	 artifact was lacking. It took the efforts of a brave and determined set of
	 heavy electron pioneers\, to overcome this resistance and change the mind-
	set.  Reflecting on this history leads us to the interesting question &#821
	1; how might we take a different path today in embracing the new challenges
	 of correlated electron materials?\n\nToday\, we are increasingly conscious
	 of the central role of spin as a driver for heavy electron metals and supe
	rconductors – not just as the glue of pairing – but as the basi
	c fabric of these materials.  Many of us suspect that the nexus  of these p
	henomena lies at quantum critical points. \n\nI'll talk about how our ideas
	 about spin and its role in the formation of the heavy electron state are c
	hanging and I will discuss the trials theorists face in seeking a proper ma
	thematical description of the spin component of strongly correlated electro
	n materials. As part of this presentation I will introduce you to two new "
	high temperature" heavy fermion superconductors\, PuCoGa5 and NpPd_2Al_5 th
	at appear to radically challenge the way we think about strongly correlated
	 superconductivity.
