Investigation of Ti nanostructures <i>via</i> laboratory scanning-free GEXRF Open
Laboratory scanning-free GEXRF in the tender X-ray range is utilized to investigate a Ti nanograting. For the first time, a reconstruction of a periodic 2D nanosample is presented based on laboratory measurements.

Experimental determination of ruthenium L-shell fluorescence yields and Coster-Kronig transition probabilities Open
The L-shell fluorescence yields and the Coster-Kronig factors of ruthenium (and the corresponding uncertainty) were determined for the first time experimentally by applying radiometrically calibrated instrumentation of the Physikalisch-Tec…

A note on improved stochastic trace estimation for fermionic string fluctuations Open
We report on the use of a stochastic trace estimator algorithm, based on mutually unbiased bases, for evaluating the trace of a matrix differential operator appearing in the context of lattice simulations for the discretized superstring wo…

Experimental and theoretical approaches for determining the K-shell fluorescence yield of carbon Open
The knowledge of atomic fundamental parameters, such as the fluorescence yields with low uncertainties, is of decisive importance in elemental quantification involving X-ray fluorescence analysis techniques. However, especially for the low…
