SUMMARY:Decoding Spatial Complexity in Strongly Correlated Electronic Syste
	ms
DESCRIPTION:Featuring Erica Carlson\, Purdue\nHosted by: David Campbell\nPo
	ster: http://physics.bu.edu/internal//files/get/020216Carlson.pdf\n\nPart o
	f the Physics Department Colloquia Series.\n\nAbstract:\n\nInside the metal
	s\, semiconductors\, and magnets of our everyday experience\, electrons are
	 uniformly distributed throughout the material.  By contrast\, electrons of
	ten form clumpy patterns inside of strongly correlated electronic systems (
	SCES) such as colossal magnetoresistance materials and high temperature sup
	erconductors.  In copper-oxide based high temperature superconductors\, sca
	nning tunneling microscopy (STM) has detected an electron nematic on the su
	rface of the material\, in which the electrons form nanoscale structures wh
	ich break the rotational symmetry of the host crystal.   These structures m
	ay hold the key to unlocking the mystery of high temperature superconductiv
	ity in these materials\, but only if the nematic also exists throughout the
	 entire bulk of the material. \n \nUsing new methods we have developed for 
	decoding these surface structures\, we find that the nematic indeed persist
	s throughout the bulk of the material.  We furthermore find that the intric
	ate pattern formation is set  by a delicate balance between disorder\, inte
	ractions\, and material anisotropy\, leading to a fractal nature of the clu
	ster pattern.  The methods we have developed can be extended to many other 
	surface probes and materials\, enabling surface probes to determine whether
	 surface structures are confined only to the surface\, or whether they exte
	nd throughout the material.
