  • Turbulent transport in the Gray Zone: A large-eddy model intercomparison study of the CONSTRAIN cold air outbreak case. 
    de Roode, Stephan R.; Frederikse, Thomas; Siebesma, A. Pier; Ackerman, Andrew S.; Chylik, Jan; Field, Paul R.; Fricke, Jens; Gryschka, Micha; Hill, Adrian; Honnert, Rachel; Krueger, Steven K.; Lac, Christine; Lesage, Andrew T.; Tomassini, Lorenzo (Washington, DC : American Geophysical Union (AGU), 2019)
    To quantify the turbulent transport at gray zone length scales between 1 and 10 km, the Lagrangian evolution of the CONSTRAIN cold air outbreak case was simulated with seven large eddy models. The case is characterized by ...
  • Twelve Rational curves on Enriques surfaces 
    Rams, Sławomir; Schütt, Matthias (New York, NY [u.a.] : Springer, 2021)
    Given d∈ N, we prove that any polarized Enriques surface (over any field k of characteristic p≠ 2 or with a smooth K3 cover) of degree greater than 12 d2 contains at most 12 rational curves of degree at most d. For d> 2 , ...
  • Twin-lattice atom interferometry 
    Gebbe, Martina; Siemß, Jan-Niclas; Gersemann, Matthias; Müntinga, Hauke; Herrmann, Sven; Lämmerzahl, Claus; Ahlers, Holger; Gaaloul, Naceur; Schubert, Christian; Hammerer, Klemens; Abend, Sven; Rasel, Ernst M. ([London] : Nature Publishing Group UK, 2021)
    Inertial sensors based on cold atoms have great potential for navigation, geodesy, or fundamental physics. Similar to the Sagnac effect, their sensitivity increases with the space-time area enclosed by the interferometer. ...
  • The twisted forms of a semisimple group over an fq-curve 
    Bitan, Rony A.; Köhl, Ralf; Schoemann, Claudia (Talence : Institut de Mathématiques de Bordeaux, Université Bordeaux, 2021)
    Let C be a smooth, projective and geometrically connected curve defined over a finite field Fq . Given a semisimple C −S-group scheme G where S is a finite set of closed points of C, we describe the set of (OS-classes of) ...
  • Twisting the N=2 string 
    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 ...
  • A twistor space action for Yang-Mills theory 
    Popov, Alexander D. (Ridge, NY : American Physical Society, 2021)
    We consider the twistor space P6≅R4×CP1 of R4 with a nonintegrable almost complex structure J such that the canonical bundle of the almost complex manifold (P6,J) is trivial. It is shown that J-holomorphic Chern-Simons ...
  • Two aspects of gauge theories : higher-dimensional instantons on cones over Sasaki-Einstein spaces and Coulomb branches for 3-dimensional N = 4 gauge theories 
    Sperling, Marcus (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2016)
    [no abstract]
  • Two-body electrodisintegration of the three-nucleon bound state with Δ-isobar excitation 
    Yuan, L.P.; Chmielewski, K.; Oelsner, M.; Sauer, Peter Ulrich; Adam, J. (College Park, MD : American Physical Society, 2002)
    Electrodisintegration of the three-nucleon bound state with two-body final states is described. The description uses nucleon degrees of freedom extended to include the excitation of a single nucleon to a Δ isobar. The ...
  • Two-center interference and ellipticity in high-order harmonic generation from H2+ 
    van der Zwan, Elmar V.; Lein, Manfred (College Park, MD : American Physical Society, 2010)
    We present a theoretical investigation into the two-center interference in aligned H2+. The influence of the laser field on the recombination step is investigated by comparing laser-induced harmonic generation with harmonic ...
  • Two-dimensional crossover and strong coupling of plasmon excitations in arrays of one-dimensional atomic wires 
    Lichtenstein, Timo; Aulbach, J.; Schäfer, J.; Claessen, R.; Tegenkamp, Christoph; Pfnür, Herbert (College Park, MD : American Physical Society, 2016)
    Dimensional crossover is of high relevance to understanding real-world quasi-one-dimensional (1D) systems. Here we study the collective excitations, measured as plasmon dispersions in an electron energy loss experiment, ...
  • 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 ...
  • Two-level metallization and module integration of point-contacted solar cells 
    Schulte-Huxel, Henning; Römer, Udo; Blankemeyer, Susanne; Merkle, Agnes; Larionova, Yevgeniya; Steckenreiter, Verena; Peibst, Robby; Kajari-Schröder, Sarah; Brendel, Rolf (Amsterdam : Elsevier, 2014)
    We present a module integration process for back junction back contact (BJBC) solar cells featuring point contacts to the back surface field (BSF). We apply two metallization layers. A first metal layer of aluminum is ...

    Recent progress in the understanding of vacuum expectation values and of infrared divergences in different regularization schemes is reviewed. Vacuum expectation values are gauge and renormalization-scheme dependent ...
  • Two-path transport measurements on a triple quantum dot 
    Rogge, M.C.; Haug, Rolf J. (College Park, MD : American Physical Society, 2008)
    As an advanced quantum system, a three terminal triple quantum dot with one lead attached to each dot allows us to simultaneously measure a transport along two different paths. Quadruple points with all three dots in ...

  • Two-phase flow in rotating hele-shaw cells with coriolis effects 
    Escher, Joachim; Guidotti, Patrick; Walker, Christoph (Zürich : European Mathematical Society Publishing House, 2013)
    The free boundary problem of a two phase flow in a rotating Hele-Shaw cell with Coriolis effects is studied. Existence and uniqueness of solutions near spheres is established, and the asymptotic stability and instability ...

    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 ...
