SUMMARY:Revealing Interactions in Complex Systems with Coherent Multi-
 Dimensional Spectroscopy\, R. G. Herb Condensed Matter Seminar\, Jeffr
 ey Davis\, Swinburne University of Technology-Melbourne Australia
DESCRIPTION:Multidimensional coherent spectroscopies are designed to i
 dentify and quantify interactions between quasi-particles. The nature 
 of these interactions can vary from simple population transfer or cohe
 rent coupling\, through to more complex higher-order correlations and 
 many-body effects. The challenge with these measurements is being able
  to extract the salient information. We have developed methods that se
 lectively probe specific quantum pathways\, which allows us to access 
 details of weak interactions that are otherwise hidden in complex syst
 ems. In this seminar\, I will discuss some of the insights we have bee
 n able to gain in a range of sample systems\, from photosynthetic ligh
 t-harvesting complexes\, through to coupled semiconductor nanostructur
 es\, and high-Tc cuprate superconductors.
