SUMMARY:Visualizing Complex Electronic Quantum Matter
DESCRIPTION:Featuring J. C. Seamus Davis\nHosted by: Anders Sandvik\n\nPart
	 of the Physics Department Colloquia Series.\n\nI will describe recent deve
	lopments of low temperature 'Spectroscopic Imaging' STM techniques for tran
	sition metal oxides. They allow us to visualize the Complex Electronic Quan
	tum Matter in such systems\, directly at the atomic scale. As an example\, 
	we will visually explore the strange and beautiful nanoscale electronic str
	ucture of High-Tc Superconductors. One of the most startling discoveries wa
	s the intense Superconducting Pair Energy Disorder at nanoscale. Another wa
	s strong scattering and quantum-mixing of delocalized states producing beau
	tiful Quantum Interference Patterns. Yet another was the impact of Electron
	-Lattice Interactions disordered at the atomic scale. And individual impuri
	ty atom mapping techniques now reveal how Individual Dopant Atoms generate 
	most of these forms of nanoscale electronic disorder. A quite different sor
	t of discovery was the spontaneous electronic reorganization into 4X4 'Chec
	kerboard' States inside vortex cores and at very low doping. We will discus
	s the structure and potential significance of these 'checkerboard' ordering
	 phenomena and the emerging overall picture of real-space electronic struct
	ure in high-Tc cuprates.
