Multispectroscopic Study of Single Xe Clusters Using XFEL Pulses

X-ray free-electron lasers (XFELs) deliver ultrashort coherent laser pulses in the X-ray spectral regime, enabling novel investigations into the structure of individual nanoscale samples. In this work, we demonstrate how single-shot small-angle X-ray scatt ...

Probing Molecular Chirality by Orbital-Angular-Momentum-Carrying X-ray Pulses

A twisted X-ray beam with orbital angular momentum is employed in a theoretical study to probe molecular chirality. A nonlocal response description of the matter-field coupling is adopted to account for the field short wavelength and the structured spatial ...

Broadband Efficient Soliton Microcombs in Pulse-Driven Photonic Microresonators

Tobias Kippenberg, Junqiu Liu, Tobias Herr, Miles Henry Anderson, Sylvain Karlen

Broadband single-soliton based frequency combs, with a detectable repetition rate of 28 GHz, are efficiently generated through pulse-driving of a chip-based Si3N4 microresonator. We observe an influence of the pulse-driving rate on the comb mode linewidth. ...

Real-Time Dynamics of the Formation of Hydrated Electrons upon Irradiation of Water Clusters with Extreme Ultraviolet Light

Marcel Drabbels, Andrew Daniel Bonnar Clark, Verónica Oliver Álvarez de Lara

Free electrons in a polar liquid can form a bound state via interaction with the molecular environment. This so-called hydrated electron state in water is of fundamental importance, e.g., in cellular biology or radiation chemistry. Hydrated electrons are h ...

Symmetry breakdown of electron emission in extreme ultraviolet photoionization of argon

Eugenio Ferrari

Short wavelength free-electron lasers (FELs), providing pulses of ultrahigh photon intensity, have revolutionized spectroscopy on ionic targets. Their exceptional photon flux enables multiple photon absorptions within a single femtosecond pulse, which in t ...

Spin polarization and attosecond time delay in photoemission from solids

Mauro Fanciulli

In the photoemission process electrons are emitted from a solid upon excitation with UV light. From the measurement of their energy and momentum, angle-resolved photoemission spectroscopy (ARPES) allows to reconstruct the electronic properties of the solid ...

Generation and measurement of sub-micrometer relativistic electron beams

Rasmus Ischebeck, Eugenio Ferrari, Christian David

The generation of low-emittance electron beams has received significant interest in recent years. Driven by the requirements of X-ray-free electron lasers, the emittance of photocathode injectors has been reduced significantly, with corresponding increase ...
