  • 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 ...

    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 ...

    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 ...
  • Liu, Yuping; Zhen, Yanzhong; Li, Taoran; Bettels, Frederik; He, Tao; Peng, Manhua; Liang, Yucang; Ding, Fei; Zhang, Lin (Weinheim : Wiley-VCH, 2020)
    To unlock the great potential of lithium metal anodes for high-performance batteries, a number of critical challenges must be addressed. The uncontrolled dendrite growth and volume changes during cycling (especially, at ...
  • Canuel, B.; Abend, S.; Amaro-Seoane, P.; Badaracco, F.; Beaufils, Q.; Bertoldi, A.; Bongs, K.; Bouyer, P.; Braxmaier, C.; Chaibi, W.; Christensen, N.; Fitzek, F.; Flouris, G.; Gaaloul, N.; Gaffet, S.; Garrido Alzar, C.L.; Geiger, R.; Guellati-Khelifa, S.; Hammerer, K.; Harms, J.; Hinderer, J.; Holynski, M.; Junca, J.; Katsanevas, S.; Klempt, C.; Kozanitis, C.; Krutzik, M.; Landragin, A.; Làzaro, Roche, I.; Leykauf, B.; Lien, Y.-H.; Loriani, S.; Merlet, S.; Merzougui, M.; Nofrarias, M.; Papadakos, P.; Pereira Dos Santos, F.; Peters, A.; Plexousakis, D.; Prevedelli, M.; Rasel, E.M.; Rogister, Y.; Rosat, S.; Roura, A.; Sabulsky, D.O.; Schkolnik, V.; Schlippert, D.; Schubert, C.; Sidorenkov, L.; Siemß, J.-N.; Sopuerta, C.F.; Sorrentino, F.; Struckmann, C.; Tino, G.M.; Tsagkatakis, G.; Viceré, A.; Klitzing, W. von; Woerner, L.; Zou, X. (Bristol : IOP Publ., 2020)
    Gravitational waves (GWs) were observed for the first time in 2015, one century after Einstein predicted their existence. There is now growing interest to extend the detection bandwidth to low frequency. The scientific ...

    A new theoretical model for the dielectrophoretic (DEP) fabrication of single-walled carbon nanotubes (SWCNTs) is presented. A different frequency interval for the alignment of wide-energy-gap semiconductor SWCNTs is ...
  • Gersema, Philipp (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2022)
    The creation of a quantum degenerate ensemble of heteronuclear molecules with dominant dipole-dipole interactions, is considered to be instrumental for studying and understanding strongly correlated many-body systems. The ...
  • Koch, Philip (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2022)
    Gravitational wave detectors are highly sensitive instruments to measure gravitational waves. To increase their observation time and decrease maintenance and upgrade periods, newly developed improvements need to be tested ...

  • Tanzi, Roberto; Giulini, Domenico (Berlin ; Heidelberg : Springer, 2021)
    We investigate the asymptotic symmetry group of a scalar field minimally-coupled to an abelian gauge field using the Hamiltonian formulation. This extends previous work by Henneaux and Troessaert on the pure electromagnetic ...
