Ultrafast electronic dynamics and electron-nuclear coupling via linear and non-linear x-ray probing

Jon Marangos (Imperial College London)

Place: 'Isabel Rodríguez' room (215, second floor), IMDEA Nanociencia.

Abstract:

The talk will cover recent research in our group and in our collaborations at the FLASH and LCLS XFELs on:

Time resolved x-ray spectroscopy of exciton dynamics in organic photovoltaic materials
Tracking electron-nuclear coupling in a molecule undergoing charge migration via x-ray pump-probe spectroscopy
Attosecond XFEL pulses applied to impulsive x-ray stimulated Raman in liquid water – a new non-linear x-ray tool for attosecond science
The impulsive response of molecules to an x-ray excitation: Attosecond pump-probe x-ray measurements

At the end I will give a brief overview of the UK XFEL Conceptual Design and Options Analysis project.

Short biography:

Jon Marangos graduated with a BSc in Physics from Imperial College in 1982 where he remained for his PhD completed in 1986. In 1990 he was appointed an EPSRC Advanced Fellow during which time he was a Visiting Researcher at NIST, Gaithersburg USA and a Visiting Professor at the University of Tokyo. He was appointed a Lecturer in Physics at Imperial in 1995 and a Reader in 1999. In 2002 he was made Professor of Laser Physics and subsequently appointed to the Lockyer Chair in Physics. Currently he is the Director of the Blackett Laboratory Laser Consortium having served as the Head of the Quantum Optics and Laser Science Group from 2003-2008. He is the Principal Investigator of the EPSRC Programme Grant "Attosecond Electron Dynamics in Molecular and Condensed Phase Matter" (starting 2011) and has been awarded an ERC Advanced Grant on "Attosecond Science by Transmission and Emission of X-rays (ASTEX)" (starting 2012).
