Time-resolved quantum beats in the fluorescence of helium resonantly excited by XUV radiation
AC LaForge, A Benediktovitch, V Sukharnikov +18
We report on the observation of time-resolved quantum beats in the helium fluorescence from the transition 1s3p -> 1s2s, where the initial state is excited by XUV free-electron las…
Photoelectron Circular Dichroism of a Model Anionic System
Anton N. Artemyev, Eric Kutscher, Philipp V. Demekhin
Photoelectron circular dichroism in the one-photon detachment of a model methane-like chiral anionic system is studied theoretically by the single center method. The computed chira…
Multi-Attribute Relation Extraction (MARE) -- Simplifying the Application of Relation Extraction
Lars Klöser, Philipp Kohl, Bodo Kraft +1
Natural language understanding's relation extraction makes innovative and encouraging novel business concepts possible and facilitates new digitilized decision-making processes. Cu…
STAMP 4 NLP -- An Agile Framework for Rapid Quality-Driven NLP Applications Development
Philipp Kohl, Oliver Schmidts, Lars Klöser +3
The progress in natural language processing (NLP) research over the last years, offers novel business opportunities for companies, as automated user interaction or improved data an…
Resonance-enhanced multiphoton ionization in the x-ray regime
Aaron C. LaForge, Sang-Kil Son, Debadarshini Mishra +16
Here, we report on the nonlinear ionization of argon atoms in the short wavelength regime using ultraintense x rays from the European XFEL. After sequential multiphoton ionization,…
Detection of quantum-vacuum field correlations outside the light cone
Francesca Fabiana Settembrini, Frieder Lindel, Alexa Marina Herter +2
According to quantum field theory, empty space -- the ground state of the theory with all real excitations removed -- is not empty at all, but filled with quantum-vacuum fluctuatio…
