  • El Guernaoui, O.; Reuder, J.; Esau, I.; Wolf, T.; Maronga, B. (Dordrecht : Springer Netherland, 2019)
    We investigate the scaling for decaying turbulence kinetic energy (TKE) in the free-convective boundary layer, from the time the surface heat flux starts decaying, until a few hours after it has vanished. We conduct a set ...
  • Halbich, M.-U.; Zielke, D.; Gogolin, R.; Sauer-Stieglitz, R.; Lövenich, W.; Schmidt, J. (London : Nature Publishing Group, 2019)
    We examine the impact of sorbitol admixture to the hole-conduction polymer PEDOT:PSS [poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)] on the characteristics of PEDOT:PSS/crystalline silicon heterojunction solar ...
  • Hueter, A.; Huck, S.; Bodin, S.; Heimhofer, U.; Weyer, S.; Jochum, K.P.; Immenhauser, A. (Göttingen : Copernicus GmbH, 2019)
    Short-term hypoxia in epeiric water masses is a common phenomenon of modern marine environments and causes mass mortality in coastal marine ecosystems. Here, we test the hypothesis that during the early Aptian, platform-top ...

M. (Bristol : IOP Publishing Ltd., 2019)
    Astrophysical sources of gravitational waves, such as binary neutron star and black hole mergers or core-collapse supernovae, can drive relativistic outflows, giving rise to non-thermal high-energy emission. High-energy ...
  • Biza, Irene; Giraldo, Victor; Hochmuth, Reinhard; Sadat Khakbaz, Azimeh; Rasmussen, Chris (New York, NY : Springer International Publishing, 2016)
    This topical survey focuses on research in tertiary mathematics education, a field that has experienced considerable growth over the last 10 years. Drawing on the most recent journal publication as well as the latest ...
  • Ashton, G.; Jones, D.I.; Prix, Reinhard (Oxford : Oxford University Press (OUP), 2017)
    We observe that the periodic variations in spin-down rate and beam-width of the radio pulsar PSR B1828-11 are getting faster. In the context of a free precession model, this corresponds to a decrease in the precession ...
  • Heitzig, Jobst (Valencia : Universitat Politecnica de Valencia, 2002)
    Using the general notion of distance function introduced in an earlier paper, a construction of the finest distance structure which induces a given quasi-uniformity is given. Moreover, when the usual defining condition xy ...
  • Domrin, Andrei V.; Lechtenfeld, Olaf; Linares, Román; Maceda, Marco (Amsterdam : Elsevier B.V., 2013)
    The noncommutative baby Skyrme model is a Moyal deformation of the two-dimensional sigma model plus a Skyrme term, with a group-valued or Grassmannian target. Exact abelian solitonic solutions have been identified analytically ...
  • Kunitski, Maksim; Eicke, Nicolas; Huber, Pia; Köhler, Jonas; Zeller, S.; Voigtsberger, J.; Schlott, Nikolai; Henrichs, Kevin; Sann, H.; Trinter, F.; Schmidt, L.; Kalinin, Anton; Schöffler, M.; Jahnke, T.; Lein, Manfred; Dörner, R. (London : Nature Publishing Group, 2019)
    Wave-particle duality is an inherent peculiarity of the quantum world. The double-slit experiment has been frequently used for understanding different aspects of this fundamental concept. The occurrence of interference ...

    The laser interferometer space antenna (LISA) is a future space-based interferometric gravitational-wave detector consisting of three spacecraft in a triangular configuration. The interferometric measurements of path length ...
  • Mang, Katrin; Wick, Thomas (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019-07-19)
    In these lectures notes, the variational phase-field approach for modeling fracture propagation is edited for the usage in classes and summer schools. Basic modeling is briefly reviewed first. The main emphasis is on the ...
  • Hahn, Henning (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)
    Towards the goal of a large-scale quantum computer based on trapped ions, near-field microwaves represent a promising approach to perform the techni- cally challenging key operation of a two-qubit entangling gate. In this ...
  • Stiegemann, Deniz Ekrem (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)
    We introduce Thompson field theory, a class of toy models of conformal field theory in which Thompson's group T takes the role of a discrete analogue of the chiral conformal group. T and the related group F are discrete ...
  • Ketov, Sergei V.; Lechtenfeld, Olaf; Parkes, Andrew J. (College Park (Maryland) : American Physical Society, 1995)
    The most general homogeneous monodromy conditions in N=2 string theory are classified in terms of the conjugacy classes of the global symmetry group U(1,1)⊗openZ2. For classes which generate a discrete subgroup Γ, the ...
  • Lenells, Jonatan; Lechtenfeld, Olaf (College Park (Maryland) : American Institute of Physics, 2009)
    We consider N=2 supersymmetric extensions of the Camassa–Holm and Hunter-Saxton equations. We show that they admit geometric interpretations as Euler equations on the superconformal algebra of contact vector fields on the ...
  • Bellucci, Stefano; Krivonos, Sergey; Lechtenfeld, Olaf; Shcherbakov, Andrey (College Park (Maryland) : American Physical Society, 2008)
    We propose a unified superfield formulation of N=4 off-shell supermultiplets in one spacetime dimension using the standard N=4 superspace. The main idea of our approach is a gluing together of two linear supermultiplets ...
  • Gonzales, Marcelo; Khodaee, Sadi; Lechtenfeld, Olaf; Toppan, Francesco (College Park (Maryland) : American Institute of Physics, 2013)
    We couple dual pairs of N=8 superconformal mechanics with conical targets of dimension d and 8−d. The superconformal coupling generates an oscillator-type potential on each of the two target factors, with a frequency ...
  • Fedoruk, Sergey; Ivanov, Evgeny; Lechtenfeld, Olaf (College Park (Maryland) : American Physical Society, 2009)
    New superconformal extensions of d=1 Calogero-type systems are obtained by gauging the U(n) isometry of matrix superfield models. We consider the cases of N=1, N=2, and N=4 as one-dimensional supersymmetries. The bosonic ...
  • Galajinsky, Anton; Lechtenfeld, Olaf (College Park (Maryland) : American Physical Society, 2009)
    N=2 superconformal many-body quantum mechanics in arbitrary dimensions is governed by a single scalar prepotential which determines the bosonic potential and the boson-fermion couplings. We present a special class of such ...
