 2020-05-2709:31 [PUBDB-2020-02214] Journal Article et al 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.

Nuclear quantum effects in state-selective scattering from ring polymer molecular dynamics The journal of chemical physics 152(19), 194113 - (2020) [10.1063/5.0004179]   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. [...] Published on 2020-05-21.

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.

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.

A set of radial distribution functions were extracted from the simultaneous analysis ofEXAFS data at two absorption edges using the reverse Monte Carlo method. [...] Published on 2020-10-15.

Search for supersymmetric particles in gluino-gluino pair production events at CMS 133 pp. (2020) [10.3204/PUBDB-2020-02176] = Dissertation, University of Hamburg, 2019   A search for gluino pair production with events using 35.9 fb−1of data from ppcollisions at a center-of-mass energy of 13 TeV in 2016 is presented. Two differentcascade decay modes of gluinos are considered, and separate analyses for each of themodels are performed [...] OpenAccess: PhDthesisAkshanshSUSY - PDF PDF (PDFA); PhDthesisAkshanshSUSY-new - PDF PDF (PDFA); 2020-05-2011:32 [PUBDB-2020-02174] Journal Article et al High-pressure structural systematics in samarium up to 222 GPa   OpenAccess: PDF PDF (PDFA); 2020-05-1914:05 [PUBDB-2020-02166] Preprint/Report et al Superradiant Cherenkov-Wakefield Radiation as THz Source for FEL Facilities [arXiv:2005.05640; DESY-20-081]   An electron beam passing through a tube which is lined on the inside with a dielectric layer will radiate energy in the THz range due to the interaction with the boundary. The resonant enhancement of certain frequencies is conditioned by structure parameters as tube radius and permittivity of the dielectric layer.
