[ADP-25-3/T1265; DESY-25-020; Liverpool LTH 1395; arXiv:2502.00325]
41st International Symposium on Lattice Field Theory, Lattice 2024, LiverpoolLiverpool, United Kingdom, 28 Jul 2024 - 3 Aug 20242024-07-282024-08-03 Proceedings of Science / International School for Advanced Studies (LATTICE2024), 304 () [10.22323/1.466.0304]  GO
Single-spin asymmetries observed in polarised deep-inelastic scattering are important probes of hadron structure. The Sivers asymmetry provides information about the transverse momentum of the struck quark and can be related to final-state interactions. [...]

Structure and properties of tubular structures based on the quaternary misfit layered compound Sm$_{1− x}$ Y$_x$S–TaS$_2$
RSC Advances 15(13), 9605 - 9617 () [10.1039/D5RA00780A]  GO
Misfit layered compounds (MLCs) are incommensurate super-lattices made up of two repeating subunits and are promising for different applications due to the possibility of a synergetic combination of the properties of the employed sublayers. A means of fine-tuning a specific MLC is to alloy one of the elements in the system [...]

Lattice-Matched Ta$_3$N$_5$/Nb$_5$N$_6$ Interface Enables a Bulk Charge Separation Efficiency of Close to 100%
The interface between the semiconductor light absorberand the metal electrode is critical for facilitating the extraction ofphotogenerated charges in photoelectrodes. Achieving a lattice-matchedsemiconductor/electrode interface with low defect density is highlydesirable but remains a challenge for Ta3N5 photoanodes. [...]

Global analysis of fragmentation functions to charged hadrons with high-precision data from the LHC
[arXiv:2407.04422]
Fragmentation functions (FFs) are essential nonperturbative QCD inputs for predicting hadron production cross sections in high energy scatterings. In this study, we present a joint determination of FFs for light charged hadrons through a global analysis at next-to-leading order (NLO) in QCD. [...]

Development of high-average-power laser plasma accelerators driven by industrial Yb lasers
160 pp. () [10.3204/PUBDB-2025-01174] = Dissertation, University of Hamburg, 2024  GO
Over the past two decades, laser plasma accelerators (LPAs) have emerged as a groundbreakingtechnology with immense potential for electron acceleration. Their ability to sustainexceptionally high accelerating gradients, on the order of 100 GV/m, and provide electronbunches with only few femtoseconds duration, promises a compact, cost-effective solutionfor numerous industrial, commercial, and medical applications.

Particle Loss by Touschek Effect in a Storage Ring
[DESY-67-005]
A formula for the loss rate of electrons from a stored beam due to the so-called "Touschek Effect" is derived starting with the exact M~ller scattering crosssection. For rectangular distribution of transverse momentum, this formula is integrated explicitly. [...]

Capturing ultrafast molecular motions and lattice dynamics in spin crossover film using femtosecond diffraction methods
A comprehensive insight into ultrafast dynamics of photo-switchable materials is desired for efficient control of material properties through light excitation. Here, we study a polycrystalline spin crossover thin film as a prototypical example and reveal the sequential photo-switching dynamics, from local molecular rearrangement to global lattice deformation.
