Researcher
Xinhua Xie is a staff scientist at the Laboratory for Non-linear Optics at the Paul Scherrer Institute (PSI) in Switzerland. He holds a PhD in Physics (2007) from TU Wien and completed his MSc (2004) at Shanghai Institute of Optics and Fine Mechanics, China, and BSc (2001) at University of Science and Technology of China. His institutional responsibilities include installation and maintenance of SwissFEL experimental lasers, development of diagnostics for XUV-THz wavelength ranges, and conducting user operations at SwissFEL. Education: BSc in Physics (2001), University of Science and Technology of China MSc in Physics (2004), Shanghai Institute of Optics and Fine Mechanics PhD in Physics (2007), TU Wien Xinhua Xie’s research focuses on ultrafast spectroscopy of electron and nuclear dynamics in atoms and molecules under ultrashort laser and X-ray pulses , aiming to uncover the role of these dynamics in light-induced processes. His recent publications emphasize Rydberg electron dynamics, frustrated tunneling ionization, quantum control via interferometric techniques, and polarization-dependent inner-shell excitations. He contributes to the development of advanced laser systems, including sub-5fs violet pulses and self-compression methods in ambient air. Key trends in his work include strong-field quantum control , electron recollision processes , and time-resolved molecular imaging . His team at PSI explores applications in magnetic scattering, stimulated Raman spectroscopy, and nonlinear optical phenomena like second harmonic generation under extreme conditions. Scientific Awards: No awards or honors explicitly mentioned As a staff scientist, Xie collaborates on SwissFEL experimental infrastructure and engages in both independent and team-based research. His lab provides diagnostics support for XUV-THz laser systems and participates in international collaborations for attosecond-scale studies of molecular dimers and Rydberg state formation.
