In this work we present a node-level performance analysis of an adaptive resolution scheme (AdResS) implemented in ls1 mardyn . This is relevant in simulations involving a very large number of particles or long timescales, because it lowers the computational effort required to calculate short-range interactions in molecular dynamics [...]

Al2O3 is a promising material in integrated optics due to its extensive transparency window, spanning from ultraviolet (200 nm) to infrared (5500 nm), and its low optical propagation loss across this spectrum. Its high solubility for rare earth elements enables the incorporation of various dopants, making it a particularly suitable host material for integrated optical rare earth amplifiers and lasers.

Machine Unlearning describes the challenge of forgetting data points that were used for an initial training of a machine learning model. Data privacy concerns as well as safety of sensitive learning data are the driving motivation for the emergence of this field. [...]

Laser-driven accelerators hold the unique potential to significantly reduce the physical size and the costs of e.g. future synchrotron-injectors or free-electron lasers (FEL) [1], [2]. [...]

The KALDERA laser at DESY will drive a laser-plasma accelerator with up to kHz-level repetition rates [1]. The setup and commissioning of the first project phase of the Ti:Sa based CPA laser, aiming for 100 Hz, 0.5 J, <30 fs pulses, has taken place during the last two years. [...]

The two most notable methods for producing short laser pulses are mode-locked and Q-switched lasers. While mode-locked lasers generate pulses in the pico- (ps) to femtosecond (fs) range, Q-switched lasers typically produce pulses at the nanosecond (ns) or 100 ps level [1]. [...]

Ultrafast molecular phenomena, such as inter- and intramolecular energy transfer, play a pivotal role in determining the final functionality of photoactive biochemically-relevant systems. Photosynthesis is a notable example [1]. [...]

Laser-plasma acceleration (LPA) [1] is rapidly evolving from proof-of-principle experiments to stable and reliable accelerator operation. The ability of LPA to deliver high-quality, high-energy electron bunches in a compact setup has been demonstrated in numerous experiments over the last two decades [2]–[4]. [...]

Ultraviolet (UV) radiation plays a pivotal role in initiating photochemical and photobiological processes. However, capturing the initial stages of molecular dynamics that occur immediately after UV light absorption presents a significant challenge. [...]

Two-photon microscopy (2PM) is a vital imaging tool for modern life science [1]. As enabling technology, compact Yb:fiber lasers combined with novel labelling techniques have emerged as rapidly advancing sources for high-performance biomedical 2PM applications [2]. [...]
