  • Cuntz, Michael; Elia, Sophia; Labbé, Jean-Philippe ([Cham (ZG)] : [Springer International Publishing AG], 2021)
    A catalogue of simplicial hyperplane arrangements was first given by Grünbaum in 1971. These arrangements naturally generalize finite Coxeter arrangements and also the weak order through the poset of regions. The weak order ...
  • Godin, Thomas; Sader, Lynn; Khodadad Kashi, Anahita; Hanzard, Pierre-Henry; Hideur, Ammar; Moss, David J.; Morandotti, Roberto; Genty, Goery; Dudley, John M.; Pasquazi, Alessia; Kues, Michael; Wetzel, Benjamin (Abingdon : Taylor & Francis Group, 2022)
    The need to measure high repetition rate ultrafast processes cuts across multiple areas of science. The last decade has seen tremendous advances in the development and application of new techniques in this field, as well ...
  • Erné, Marcel (Basel : Springer, 2022)
    A nucleus on a meet-semilattice A is a closure operation that preserves binary meets. The nuclei form a semilattice N A that is isomorphic to the system NA of all nuclear ranges, ordered by dual inclusion. The nuclear ...
  • Heal, Kathryn; Kulkarni, Avinash; Sertöz, Emre Can (Cham (ZG) : Springer International Publishing AG, 2022)
    The Gauss–Manin connection of a family of hypersurfaces governs the change of the period matrix along the family. This connection can be complicated even when the equations defining the family look simple. When this is the ...
  • Erné, Marcel; Picado, Jorge; Pultr, Aleš (Basel : Springer, 2022)
    We study residuated homomorphisms (r-morphisms) and their adjoints, the so-called localizations (or l-morphisms), between implicative semilattices, because these objects may be characterized as semilattices whose unary ...
  • Javvaji, Brahmanandam; Zhuang, Xiaoying; Rabczuk, Timon; Mortazavi, Bohayra (Weinheim : Wiley-VCH, 2022)
    Accurate examination of electricity generation stemming from higher-order deformation (flexoelectricity) in 2D layered materials is a highly challenging task to be investigated with either conventional computational or ...
  • Hannig, Stephan; Pelzer, L.; Scharnhorst, N.; Kramer, J.; Stepanova, M.; Xu, Z.T.; Spethmann, N.; Leroux, I.D.; Mehlstäubler, Tanja E.; Schmidt, Piet O. (American Institute of Physics : [S.l.], 2019)
    With the advent of optical clocks featuring fractional frequency uncertainties on the order of 10−17 and below, new applications such as chronometric leveling with few-centimeter height resolution emerge. We are developing ...

    We present a systematic study on the benefit of the implementation of poly-Si on oxide (POLO) or related junctions into p-type industrial Si solar cells as compared with the benchmark of Passivated Emitter and Rear Cell ...
  • Amstutz, Samuel; Wick, Thomas (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2022-09-21)
    These lecture notes accompany a refresher course in applied mathematics with a focus on numerical concepts (Part I), numerical linear algebra (Part II), numerical analysis, Fourier series and Fourier transforms (Part ...
  • Rahlves, Charlotte; Beyrich, Frank; Raasch, Siegfried (Katlenburg-Lindau : Copernicus, 2022)
    Doppler-lidar scan techniques for wind profiling rely on the assumption of a horizontally homogeneous wind field and stationarity for the duration of the scan. As this condition is mostly violated in reality, detailed ...
  • Babushkin, Ihar; Morgner, Uwe; Demircan, Ayhan (Bristol : IOP Publ., 2020)
    Here we study transformation of waveshapes of photons under the action of the linear logic circuits and other related architectures involving only linear optical networks and measurements. We show that the gates are working ...
  • Schinke, Carsten; Pollex, Hendrik; Hinken, David; Wolf, Martin; Bothe, Karsten; Kröger, Ingo; Nevas, Saulius; Winter, Stefan (Sèvres : Bureau International des Poids et Mesures, 2020)
    Measuring the spectral irradiance of solar radiation is required in many fields of science and technology. In this work, we present an in-depth discussion of the measuring procedure and required corrections for such ...
  • Heinze, Joscha (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2022)
    The next generation of gravitational-wave detectors (GWD), formed by the Einstein Telescope (ET) and Cosmic Explorer (CE), aims for improving the currently achieved sensitivities by one order of magnitude which requires ...
  • Edler, Daniel (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2022)
    Recent theoretical and experimental breakthrough results have revealed the importance of beyond-mean-field contributions in weakly-interacting systems when the mean-field energy is quasi-canceled due to the presence of ...
  • Kumar, Kaushlendra (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2022)
    Diese Doktorarbeit befasst sich mit der Analyse einiger Yang-Mills-Lösungen auf vier dimensionalen de Sitter Raum. Die konforme Äquivalenz dieses Raums mit einem endlichen Lorentz-Zylinder über der 3-Sphäre und auch mit ...
  • Dai, Yi; Basu, Sukanta; Maronga, Björn; de Roode, Stephan R. (Dordrecht [u.a.] : Springer Science + Business Media B.V, 2020)
    We have identified certain fundamental limitations of a mixing-length parametrization used in a popular turbulent kinetic energy-based subgrid-scale model. Replacing this parametrization with a more physically realistic ...
  • Thorn, Jessic P. R.; Klein, Julia A.; Steger, Cara; Hopping, Kelly A.; Capitani, Claudia; Tucker, Catherine M.; Nolin, Anne W.; Reid, Robin S.; Seidl, Roman; Chitale, Vishwas .S.; Marchant, Robert (Wolfville, Nova Scotia : Resilience Alliance, 2020)
    Mountain social-ecological systems (MtSES) provide crucial ecosystem services to over half of humanity. However, populations living in these highly varied regions are now confronted by global change. It is critical that ...
  • Helmich, Lailah; Walter, Dominic C.; Bredemeier, Dennis; Schmidt, Jan (Weinheim : Wiley-VCH, 2020)
    Stacks of hydrogen-lean aluminum oxide, deposited via plasma-assisted atomic-layer-deposition, and hydrogen-rich plasma-enhanced chemical vapor-deposited silicon nitride (SiNx) are applied to boron-doped float-zone silicon ...
  • Mahmoodian, Sahand; Calajó, Guiseppe; Chang, Darrick E.; Hammerer, Klemens; Sørensen, Anders S. (College Park, Md. : APS, 2020)
    We theoretically study the few- and many-body dynamics of photons in chiral waveguides. In particular, we examine pulse propagation through an ensemble of N two-level systems chirally coupled to a waveguide. We show that ...
  • Tanzi, Roberto; Giulini, Domenico (Berlin ; Heidelberg : Springer, 2020)
    We investigate the asymptotic symmetry group of the free SU(N )-Yang-Mills theory using the Hamiltonian formalism. We closely follow the strategy of Henneaux and Troessaert who successfully applied the Hamiltonian formalism ...
