Monitoring the evolution of relative product populations at early times during a photochemical reaction
Joao Pedro Figueira Nunes, Lea Maria Ibele, Shashank Pathak +31
Identifying multiple rival reaction products and transient species formed during ultrafast photochemical reactions and determining their time-evolving relative populations are key…
X-ray Free Electron Laser Studies of Electron and Phonon Dynamics of Graphene Adsorbed on Copper
Hirohito Ogasawara, Han Wang, Jörgen Gladh +23
We report optical pumping and X-ray absorption spectroscopy experiments at the PAL free electron laser that directly probe the electron dynamics of a graphene monolayer adsorbed on…
Rehybridization dynamics into the pericyclic minimum of an electrcyclic reaction imaged in real-time
Yusong Liu, David M. Sanchez, Matthew R. Ware +17
Electrocyclic reactions are characterized by the concerted formation and cleavage of both σ and π bonds through a cyclic structure. This structure is known as a pericyclic transiti…
Direct visualization of ultrafast lattice ordering triggered by an electron-hole plasma in 2D perovskites
Hao Zhang, Wenbin Li, Joseph Essman +18
Direct visualization of ultrafast coupling between charge carriers and lattice degrees of freedom in photo-excited semiconductors has remained a long-standing challenge and is crit…
Simultaneous Observation of Carrier-Specific Redistribution and Coherent Lattice Dynamics in 2H-MoTe with Femtosecond Core-Level Spectroscopy
Andrew R. Attar, Hung-Tzu Chang, Alexander Britz +12
We employ few-femtosecond extreme ultraviolet (XUV) transient absorption spectroscopy to reveal simultaneously the intra- and interband carrier relaxation and the light-induced str…
Nonlinear coherence effects in transient-absorption ion spectroscopy with stochastic extreme-ultraviolet free-electron laser pulses
Thomas Ding, Marc Rebholz, Lennart Aufleger +21
We demonstrate time-resolved nonlinear extreme-ultraviolet absorption spectroscopy on multiply charged ions, here applied to the doubly charged neon ion, driven by a phase-locked s…
Strong-field extreme-ultraviolet dressing of atomic double excitation
Christian Ott, Lennart Aufleger, Thomas Ding +21
We report on the experimental observation of strong-field dressing of an autoionizing two-electron state in helium with intense extreme-ultraviolet laser pulses from a free-electro…
