X-ray driven displacive excitation of coherent phonons
Oleg Dogadov, Remi Claude, Christoph Emeis +29
Modulating electron-phonon coupling offers a route to control structural displacements and tune material functionality. Valence-to-conduction band transitions, however, provide lim…
Light-Stabilized Metastable Electronic State in NiO with Enhanced Orbital Hybridization
Thomas C. Rossi, Fabio G. Santomauro, Lars Mewes +19
Light-driven control of electronic structure in correlated metal oxides offers new opportunities for optimizing materials used in photovoltaic and photoelectrochemical technologies…
All-Optical Single-Shot Temporal Characterization of SASE FEL Pulses Using Double-Blind Holography
A. Azzolin, O. Cannelli, K. -F. Wong +31
X-ray Free-electron lasers (XFELs) deliver ultrashort and ultrabright radiation in a photon-energy range spanning from extreme ultraviolet to hard X-rays. Supporting pulse duration…
Engineering High-Order Harmonic Generation through Gas Confinement at Sub-Millimeter Lengths
Agata Azzolin, Gaia Giovannetti, Oliviero Cannelli +23
Attosecond light sources based on high-order harmonic generation (HHG) constitute to date the only table-top solution for producing coherent broadband radiation covering the spectr…
X-ray Absorption Linear Dichroism at the Ti K-edge of TiO2 anatase single crystals
T. C. Rossi, D. Grolimund, M. Nachtegaal +9
Anatase TiO2 (a-TiO2) exhibits a strong X-ray absorption linear dichroism with the X-ray incidence angle in the pre-edge, the XANES and the EXAFS at the titanium K-edge. In the pre…
