    The analysis of entangled atomic ensembles and their application for interferometry beyond the standard quantum limit requires an accurate determination of the number of atoms. We present an accurate fluorescence detection ...

    Several critical issues, such as the shuttling effect and the sluggish reaction kinetics, exist in the design of high-performance lithium–sulfur (Li-S) batteries. Here, it is reported that nitrogen doping can simultaneously ...

    Contact interaction of two bodies can be modeled using the penalty function approach while its accuracy and robustness are directly associated with the geometry of contact bodies. Particularly, in the research fields of ...

    In this work, we propose a parameter estimation framework for fracture propagation problems. The fracture problem is described by a phase-field method. Parameter estimation is realized with a Bayesian approach. Here, the ...
  • Gulbrandsen, Martin G.; Halle, Lars H.; Hulek, Klaus (Berlin : Deutsche Mathematiker-Vereinigung e.V., 2019)
    We present a Geometric Invariant Theory (GIT) con-struction which allows us to construct good projective degenerationsof Hilbert schemes of points for simple degenerations. A comparisonwith the construction of Li and Wu ...

    We report on optical investigations of MOVPE-grown InGaAs/GaAs quantum dots emitting at the telecom O-band that were integrated ontouniaxial piezoelectric actuators. This promising technique, which does not degrade the ...
  • Hartmann, Alexander K.; Melchert, Oliver; Norrenbrock, Christoph (Basel : MDPI, 2019)
    Spin glasses are prototypical random systems modelling magnetic alloys. One important way to investigate spin glass models is to study domain walls. For two dimensions, this can be algorithmically understood as the calculation ...

(Washington, DC : NAS, 2019)
    A massive atmospheric release of radioactive 106Ru occurred in Eurasia in 2017, which must have been caused by a sizeable, yet undeclared nuclear accident. This work presents the most compelling monitoring dataset of this ...
  • Oppermann, F.; Wustelt, P.; Florin, T.; Mhatre, S.; Gräfe, S.; Paulus, G.G.; Lein, M. (Bristol : Institute of Physics Publishing, 2020)
    Using quantum-mechanical, one-dimensional, non-Born-Oppenheimer simulations we study the control over the strong-field dynamics of the helium hydride molecular ion HeH+ due to interaction driven by short and strong two-color ...
  • Gross, Günther (Stuttgart : E. Schweizerbart Science Publishers, 2020)
    A one-dimensional boundary layer model was combined with a routine to calculate surface temperatures on road bridges. Forced by reanalysis data for the year 2016, simulations were performed for two bridges 80 and 130 m in ...
  • Fennen, Michael; Giulini, Domenico (Bristol : Institute of Physics Publishing (IOP), 2020)
    In this paper we propose to use Lie sphere geometry as a new tool to systematically construct time-symmetric initial data for a wide variety of generalised black-hole configurations in lattice cosmology. These configurations ...
  • Schwanbeck, Julian; Oehmig, Ines; Dretzke, Jerôme; Zautner, Andreas E.; Groß, Uwe; Bohne, Wolfgang (London : BioMed Central, 2020)
    Background: Motility in bacteria forms the basis for taxis and is in some pathogenic bacteria important for virulence. Video tracking of motile bacteria allows the monitoring of bacterial swimming behaviour and taxis on ...
  • Zinder, Evgeny; Zhang, Ziyu (Hoboken, NJ : Wiley, 2020)
    We construct non-trivial L-equivalence between curves of genus one and degree five, and between elliptic surfaces of multisection index five. These results give the first examples of L-equivalence for curves (necessarily ...

    Copper-indium-gallium-diselenide (CIGS) thin-film solar cells suffer from high recombination losses at the back contact and parasitic absorption in the front-contact layers. Dielectric passivation layers overcome these ...

    In the search for highly transparent and non-toxic alternative front layers replacing state-of-the-art CdS in Cu(In,Ga)Se2 thin-film solar cells, alternatives rarely exceed reference devices in terms of efficiency. Full-area ...

    The dynamics of deep sea explosive eruptions, the dispersion of the pyroclasts, and how submarine eruptions differ from the subaerial ones are still poorly known due to the limited access to sea environments. Here, we ...

    In recent years, lanthanide-doped nanothermometers have been mainly used in thin films or dispersed in organic solvents. However, both approaches have disadvantages such as the short interaction lengths of the active ...
