Node-Level Performance and Energy Characterization of Flagship Science Applications on SuperMUC-NG Phase 2
Salvatore Cielo, Elmira Birang, Alexander Pöppl +5
We present a systematic performance and energy-efficiency characterization of five flagship scientific workloads on SuperMUC-NG phase 2, the 28 PetaFLOPs system at the Leibniz Supe…
Diffraction patterns in attosecond photoionization time delay
Sajad Azizi, Mohamed El-Amine Madjet, Zheng Li +2
Upon absorbing a photon, the ionized electron sails through the target force field in attoseconds to reach free space. This navigation probes details of the potential landscape tha…
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…
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…
Investigation of Confinement Induced Resonance in Atomic Waveguides with Different Geometries by Quantum Monte Carlo Methods
Sajad Azizi, Shahpoor Saeidian
We have investigated the quantum dynamics of two ultracold bosons inside an atomic waveguide for two different confinement geometries (cigar-shaped and toroidal waveguides) by quan…
