Ever since the invention of the laser 50 years ago, scientists have been striving to extend coherent laser-like beams into the x-ray region of the spectrum. Very recently, we used tabletop femtosecond lasers to create bright beams of x-rays at wavelengths <10Å, by harnessing a new ability to manipulate electrons on their natural, attosecond (10^-18s), time-scales. Ultrafast X-rays are powerful probes of the nanoworld. They penetrate thick samples and can image small objects. This talk will also highlight how ultrafast x-rays can capture the coupled motions of charges, spins, phonons and photons that underlie function in nanosystems on the fastest timescales. Experiences regarding technology transfer can also be discussed. 1. Popmintchev et al, Science 336, 1287 (2012).
Margaret is now a Fellow of JILA and a Distinguished Professor in Physics at the University of Colorado. She runs a joint, multi-disciplinary, research group with her husband, Prof. Henry Kapteyn. She received her B.S and M.S. degrees from University College Cork, Ireland, and her Ph.D. degree from UC Berkeley. Prof. Murnane with her students and collaborators uses coherent beams of laser and x-ray light to capture the fastest dynamics in molecules and materials at the nanoscale. She is a Fellow of the Optical Society of America, the American Physical Society, and the AAAS. She was elected to the National Academy of Sciences in 2004, and the American Academy of Arts and Sciences in 2006. She was awarded a John D. and Catherine T. MacArthur Fellowship in 2000. As well as the Lamb Award, Margaret and Henry also shared the 2009 Ahmed Zewail Award of the American Chemical Society, the 2010 Schawlow Prize of the American Physical Society, and the 2010 R.W. Wood Prize of the Optical Society of America. Margaret is very interested in increasing diversity in science and engineering, and currently chairs the Presidents Committee for the Medal of Science.
