Abstract：

Understanding and ultimately controlling the properties of matter, from molecular to quantum systems, requires imaging their elementary excitations on their natural time and length scales of femtoseconds and nanometers. In order to achieve this goal, we developed scanning probe microscopy with ultrafast and shaped laser pulses for multiscale spatio-temporal optical nano-imaging. In corresponding ultrafast movies, we resolve the fundamental quantum dynamics from the fastest few-femtosecond coherent to the nanosecond thermal transport regime.

Bio of the Lecturer：

Markus Raschke is professor at the Department of Physics and JILA at the University of Colorado at Boulder. His research is on the development and application of nano-scale nonlinear and ultrafast spectroscopy to control the light-matter interaction on the nanoscale. These techniques allow for imaging structure and dynamics of molecular and quantum matter with nanometer spatial resolution. He received his PhD in 2000 from the Max-Planck Institute of Quantum Optics and the Technical University in Munich, Germany. Following a postdoc at the University of California at Berkeley, and research group leader at the Max-Born-Institute in Berlin, he became faculty member at the University of Washington in 2006, before moving to the University of Colorado and JILA in 2010. He is fellow of the Optical Society of America, the American Physical Society, the American Association for the Advancement of Science, and the Explorers Club.
