• How Do Dust Devil-Like Vortices Depend on Model Resolution? A Grid Convergence Study Using Large-Eddy Simulation 

  Giersch, Sebastian; Raasch, Siegfried (Dordrecht [u.a.] : Springer Science + Business Media B.V, 2023)

  Dust devils are organized convective vortices with pressure drops of hundreds of pascals that spirally lift surface material into the air. This material modifies the radiation budget by contributing to the atmospheric ...
• Laser bioprinting of human iPSC-derived neural stem cells and neurons: Effect on cell survival, multipotency, differentiation, and neuronal activity 

  Koch, Lothar; Deiwick, Andrea; Soriano, Jordi; Chichkov, Boris (Singapore : Whioce, 2023)

  Generation of human neuronal networks by three-dimensional (3D) bioprinting is promising for drug testing and hopefully will allow for the understanding of cellular mechanisms in brain tissue. The application of neural ...
• Photon bound state dynamics from a single artificial atom 

  Tomm, Natasha; Mahmoodian, Sahand; Antoniadis, Nadia O.; Schott, Rüdiger; Valentin, Sascha R.; Wieck, Andreas D.; Ludwig, Arne; Javadi, Alisa; Warburton, Richard J. (Basingstoke : Nature Publishing Group, 2023)

  The interaction between photons and a single two-level atom constitutes a fundamental paradigm in quantum physics. The nonlinearity provided by the atom leads to a strong dependence of the light–matter interface on the ...
• Two-Level Error Estimation for the Integral Fractional Laplacian 

  Faustmann, Markus; Stephan, Ernst P.; Wörgötter, David (Berlin : De Gruyter, 2023)

  For the singular integral definition of the fractional Laplacian, we consider an adaptive finite element method steered by two-level error indicators. For this algorithm, we show linear convergence in two and three space ...
