invited talks

An atom or molecule interacting with an intense, ultrafast laser pulse is a fundamental problem in modern physics. At intensities that are approximately one-tenth an atomic unit of field (50 V/A) the physics is well described by a semi-classical 3-step model where an electron tunnel ionizes, driven by the strong-field and then rescatters with its parent core. The consequence of this physics...

169. Controlled Asymmetric Photoelectron Emission Using Electron Wavepacket Interference

oral

We demonstrate control of photoelectron emission in two-color photoionization through electron wavepacket interference, using attosecond pulse trains with either two or three pulses together with a few-cycle IR dressing field at a fixed delay.

231. Electronic Wavefunctions Probed by All-Optical Attosecond Interferometry

Dr Michael Krüger (Weizmann Institute of Science)

oral

We directly measure electron-ion scattering phase shifts in atomic systems using optical interferometry in the extreme ultraviolet domain. Our method reveals partial-wave scattering phase shifts and structural phase jumps, enabling studies of multielectron phenomena.

46. Time-resolved Orbital Imaging by Photoelectrons

Matthias Kübel (Friedrich Schiller University Jena)

04/07/2019, 11:45

oral

We demonstrate imaging of bound electron wave packets following ionization. Using a pump-probe-deflect scheme, a superposition of spin-orbit states is prepared in Ar$^+$ and a movie of the wave packet evolution is recorded.

160. Real-time Probing of the Plasmonic Response of C$_{60}$

Andrea Trabattoni (Center for Free-Electron Laser Science (CFEL), DESY)

04/07/2019, 12:00

oral

The time-dependent plasmonic response of C$_{60}$ is revealed through attosecond streaking spectroscopy. The streaking delay as a function of the electron energy shows a decaying trend including zero-crossing, as a signature of photo-induced collective excitation.

164. Attosecond Quantum State Reconstruction of Autoionizing Electron Wavepackets

Mr Hugo Laurell (Lund University)

oral

We reconstruct the temporal evolution of the density matrix of an autoionizing electron wavepacket using attosecond quantum state reconstruction with high spectral and temporal resolution.
