　　主讲人简介：

　　Markus Raschke is Professor at the Departments of Physics, Chemistry, and JILA at the University of Colorado at Boulder. His research is on the development of new nano-scale nonlinear and ultrafast spectroscopy techniques to image and control nanoscale and correlated matter. He received his PhD in 2000 from the Max-Planck Institute of Quantum Optics and the Technical University in Munich, Germany. Following research appointments at the University of California at Berkeley, and the Max-Born-Institute in Berlin, he was on the faculty of the University of Washington, before his appointment at Boulder in 2010.

　　He is fellow of the Optical Society of America, the American Physical Society, and the American Association for the Advancement of Science. He recently won the Bessel award of the Humboldt Foundation, and the Klaus Halbach award for the development of synchrotron infrared nano-spectroscopy.

　　He has collaborated on metrology and laser development with Bruker, Anasys, Horiba, Zurich Instruments, ARS, APE, Vescent, and other companies. He has been committed to collaborations with institutions in China for over 10 years with a personal interest in mineralogy and rare earth petrology in Sichuan.

　　报告摘要：

　　Molecular and quantum state interactions at the nanoscale give rise to the function of molecular electronics, organic light-emitting diodes, photovoltaics, and biochemical processes. Optical tip-enhanced nano-imaging in combination with ultrafast lasers enables imaging the underlying electronic and vibrational excitations on their natural nanometer length and femtosecond times scales. Furthermore, the tip nano-cavity light-matter interaction provides for active control of quantum states from quantum metrology to quantum information processing.

　　Prof. Markus Raschke will introduce this emerging field of tip-enhanced scanning probe microscopy for precision spectroscopy, ultrafast-nano-imaging, and in the strong coupling limit with applications in cavity quantum electrodynamics (nano-cQED).
