Capturing Nanoscale Materials Properties Using Tabletop Coherent Soft X-Ray Beams
High harmonic generation (HHG) is a unique quantum light source with fundamentally new capabilities – producing fully spatially and temporally coherent beams with linear or circular polarization throughout the extreme ultraviolet (EUV) and soft x-ray region, all on a tabletop. This talk will introduce and review recent developments in HHG sources, as well as exciting advances in imaging and spectroscopy of materials, including full-field microscopes with sub-wavelength spatial resolution in the soft x-ray region for the first time, quantifying how nanoscale energy flow differs from bulk, characterizing how the properties of materials change with doping, measuring how fast a material can change its electronic or magnetic state, probing how spin currents can control and enhance magnetization in ultra thin films, and visualizing the dynamic band structure of material and electron-electron interactions on sub-femtosecond timescales.
About Margaret Murnane
Margaret Murnane is Director of the National Science Foundation STROBE Science and Technology Center on functional nanoimaging, a fellow at JILA and a member of the Department of Physics and Electrical and Computer Engineering at the University of Colorado Boulder.
She received her BS and MS degrees from University College Cork and her PhD degree in physics from the University of California, Berkeley, in 1989, and joined the faculty of physics at Washington State University in 1990. In 1996, Murnane moved to the University of Michigan, and in 1999, to the University of Colorado Boulder. She runs a joint research group and a small laser company with her husband, Henry Kapteyn. Her research interests have focused on ultrafast optical and x-ray science.
Murnane is a fellow of the American Physical Society, The Optical Society of America and the AAAS. Her honors include the Maria Goeppert-Mayer Award of the American Physical Society, a John D. and Catherine T. MacArthur Fellowship and election to the National Academy of Sciences, the American Academy of Arts & Sciences, the American Philosophical Society and the Royal Irish Academy.
