Breakdown of the single-collision condition for soft x-ray high harmonic generation in noble gases
(2022)High harmonic generation (HHG) in atomic gases is generally assumed to originate from photoelectrons that are not perturbed by neighboring particles. In this article, we study theoretically and experimentally the regime where this approximation breaks down. At high laser intensities, we experimentally find that producing soft X-rays beyond this single-collision condition leads to a strong reduction of the coherent HHG response and appearance ...Dataset -

Data for "Rebordering Europe in times of war: the Ukraine crisis and EU boundary change"
(2022)How has the European Union (EU) developed in reaction to the Russo-Ukrainian war, its most severe military threat since the end of the Cold War? In a ‘bordering’ analysis of political development, this article studies changes in the closure and control of the EU’s boundaries with Russia and Ukraine as well as its internal boundaries between 2013 and August 2022. It finds that the EU’s response has hitherto consisted in a regulatory process ...Dataset
