Attosecond Pulse-shaping using a seeded free-electron laser
Praveen Kumar Maroju, Cesare Grazioli, Michele Di Fraia +41
Attosecond pulses are fundamental for the investigation of valence and core-electron dynamics on their natural timescale. At present the reproducible generation and characterisatio…
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…
A new method for measuring angle-resolved phases in photoemission
Daehyun You, Kiyoshi Ueda, Elena V. Gryzlova +33
Quantum mechanically, photoionization can be fully described by the complex photoionization amplitudes that describe the transition between the ground state and the continuum state…
Local Aspects of Hydrogen-Induced Metallization of the ZnO(100) Surface
J. -C. Deinert, O. T. Hofmann, M. Meyer +2
This study combines surface-sensitive photoemission experiments with density functional theory (DFT) to give a microscopic description of H adsorption-induced modifications of the…
Ultrafast exciton formation at the ZnO(100) surface
J. -C. Deinert, D. Wegkamp, M. Meyer +3
We study the ultrafast quasiparticle dynamics in and below the ZnO conduction band using femtosecond time-resolved two-photon photoelectron spectroscopy. Above band gap excitation…
