One of the intriguing problems of modern magnetism is unravelling the non-equilibrium spin dynamics following laser excitation on the nanometer length scale. In this work the ultrafast magnetic behavior of thin Co/Pt multilayers is studied by resonant magnetic SAXS in transmission geometry [...]

For decades, copper has been introduced in CdTe devices to improve overall performance (open circuit voltage, fill factor, and series resistance). While multiple articles have reported on Cu-based defects, very little is known about how the local structure around the copper atom affects electrical performance [...]

For decades, copper has been used to improve the performance of cadmium telluride thin film solar cells. However, it has also been shown to be the main cause of metastability in CdTe [...]

The value of $α_s$($m_Z$) is determined from inclusive jet and di-jet cross sections in neutral-current deep-inelastic $ep$ scattering (DIS) measured at HERA by the H1 collaboration using next-to-next-to-leading order (NNLO) perturbative QCD predictions. Using inclusive jet and di-jet data together, the strong coupling constant is determined to be $α_s$($m_Z$) = 0.1157(20)$_{exp}$(29)$_{th}$. [...]

An additional U(1) symmetry predicted in theories beyond the Standard Model of particle physics can give rise to hidden (dark) photons. Depending on the mass and density of these hidden photons, they could account for a large fraction of the Dark Matter observed in the Universe. [...]

Higher order calculations in perturbative Quantum Field Theories often produce coupled linear systems of differential equations which factorize to first order. Here we present an algorithm to solve such systems in terms of iterated integrals over an alphabet the structure of which is implied by the coefficient matrix of the given system. [...]

The Module Management Controller (MMC) is a mandatory component of every AMC board. DESY is developing, maintaining and licensing a turn-key MMC solution that is used on several hundred boards in different facilities - on DESY's own products as well as on third-party AMC boards developed by industrial customers and project partners.With the growing number of different boards, the maintenance of the codebase becomes more and more challenging, as every improvement needs to be integrated, tested and deployed to each product containing our MMC solution.

ChimeraTK is a software framework for the development of control applications. Recently, version 02.00 of ChimeraTK's DeviceAccess, ApplicationCore and ControlSystemAdapter libraries have been released. [...]
