Depth-resolved core level spectroscopy of noncentrosymmetric solid BiPd
Understanding exotic solids is a difficult task as interactions are often hidden by the symmetry of the system. Here, we study the electronic properties of a noncentrosymmetric solid, BiPd, which is a rare material exhibiting both superconductivity and the topological phase of matter. [...]

Complex hybridization physics in $CaFe_{2}As_{2}$ - a high resolution hard x-ray photoemission study
Employing high resolution hard x-ray photoemission spectroscopy, we investigate the electronic structure of an exotic Fe-based superconductor, CaFe$_2$As$_2$, which exhibits rich temperature pressure phase diagram and dichotomy on achieving superconductivity on application of pressure. The experimental valence band spectra exhibit significant differences for experiments at different surface sensitivities. [...]

Luminosity calibration with the Van der Meer method in proton-proton collisions at the CMS experiment
LHCP2020: The Eighth Annual Conference on Large Hadron Collider Physics, LHCP2020, OnlineOnline, Online, 25 May 2020 - 30 May 20202020-05-252020-05-30
The luminosity measurement of the CMS experiment is calibrated under special beam conditions with beam separation scans called Van der Meer (VdM) scans. In a VdM scan, the two proton beams are separated transversely and moved in steps across each other. [...]

Nuclear quantum effects in state-selective scattering from ring polymer molecular dynamics
We present an efficient method to obtain initial state-selective cross sections for bimolecular reactions that can account for certain nuclear quantum effects by employing the ring polymer molecular dynamics approach. The method combines the well known quasiclassical trajectory (QCT) approach with the description of the system in an extended ring polymer phase space. [...]

Setting the photoelectron clock through molecular alignment
The interaction of strong laser fields with matter intrinsically provides a powerful tool for imaging transient dynamics with an extremely high spatiotemporal resolution. Here, we study strong-field ionisation of laser-aligned molecules, and show a full real-time picture of the photoelectron dynamics in the combined action of the laser field and the molecular interaction.

Comparison of topological charge definitions in Lattice QCD
[DESY-17-115; arXiv:1708.00696]
In this paper, we show a comparison of different definitions of the topological charge on the lattice. We concentrate on one small-volume ensemble with 2 flavours of dynamical, maximally twisted mass fermions and use three more ensembles to analyze the approach to the continuum limit. [...]
