Zero-energy photoelectric effect
Sajad Azizi, Ulf Saalmann, Jan M. Rost
We predict a near-threshold ("zero energy") peak in multi-photon ionization for a dynamical regime where the photon frequency is large compared to the binding energy of the electro…
Strong-field quantum control in the extreme ultraviolet using pulse shaping
Fabian Richter, Ulf Saalmann, Enrico Allaria +40
Tailored light-matter interactions in the strong coupling regime enable the manipulation and control of quantum systems with up to unit efficiency, with applications ranging from q…
Non-adiabatic ionization with tailored laser pulses
Sajad Azizi, Ulf Saalmann, Jan M Rost
Non-adiabatic photo-ionization is difficult to control as it relies on the derivatives of the envelope and not on phase-details of the short ionizing pulse. Here, we introduce a ca…
Semiclassical Lindblad master equation for spin dynamics
J. Dubois, Ulf Saalmann, Jan M. Rost
We derive the semi-classical Lindblad master equation in phase space for both canonical and non-canonical Poisson brackets using the Wigner-Moyal formalism and the Moyal star-produ…
Perspectives for analyzing non-linear photo ionization spectra with deep neural networks trained with synthetic Hamilton matrices
Sajal Kumar Giri, Lazaro Alonso, Ulf Saalmann +1
We have constructed deep neural networks, which can map fluctuating photo-electron spectra obtained from noisy pulses to spectra from noise-free pulses. The network is trained on s…
Proper time delays measured by optical streaking
Ulf Saalmann, Jan M Rost
The generation of a streaking spectrogram is based on energy absorption from the streaking laser. Investigating this absorption we show rigorously under which condition the measure…
