  • Does it make sense to talk about NΔ phase shifts? 
    Garcilazo, H.; Mizutani, T.; Pea, M.T.; Sauer, Peter Ulrich (College Park, MD : American Physical Society, 1990)
    The question of whether one can consistently define and extract nucleon-delta scattering parameters, phase shifts, and inelasticities from the partial-wave NN→NΔ amplitudes is discussed. We have studied the unitarity ...
  • Domain adaptation based transfer learning approach for solving PDEs on complex geometries 
    Chakraborty, Ayan; Anitescu, Cosmin; Zhuang, Xiaoying; Rabczuk, Timon (London : Springer, 2022)
    In machine learning, if the training data is independently and identically distributed as the test data then a trained model can make an accurate predictions for new samples of data. Conventional machine learning has a ...

    Frahm, Holger; Pfannmüller, M.P.; Tsvelik, A.M. (College Park (Maryland) : American Physical Society, 1998)
    An exactly soluble model describing a spin S=1 antiferromagnetic chain doped with mobile S=1/2 carriers is constructed. In its continuum limit the undoped state is described by three gapless Majorana fermions composing the ...
  • Doping-induced magnetization plateaus 
    Frahm, Holger; Sobiella, Constantin (College Park (Maryland) : American Physical Society, 1999)
    The low-temperature magnetization process of antiferromagnetic spin- S chains doped with mobile spin- (S−1/2) carriers is studied in an exactly solvable model. For sufficiently high magnetic fields the system is in a ...

    Binnewies, T.; Wilpers, G.; Sterr, U.; Riehle, F.; Helmcke, J.; Mehlstäubler, T.E.; Rasel, Ernst Maria; Ertmer, Wolfgang (American Physical Society, 2001)
    Ultracold atoms at temperatures close to the recoil limit have been achieved by extending Doppler cooling to forbidden transitions. A cloud of 40Ca atoms has been cooled and trapped to a temperature as low as 6μK by operating ...
  • Double-slit photoelectron interference in strong-field ionization of the neon dimer 
    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 ...
  • Dual conformal constraints and infrared equations from global residue theorems in N=4 SYM theory 
    Broedel, Johannes; He, Song (New York, NY : Springer International Publishing, 2010)
    Infrared equations and dual conformal constraints arise as consistency conditions on loop amplitudes in N=4 super Yang-Mills theory. These conditions are linear relations between leading singularities, which can be computed ...
  • Dual infrared limits of 6d N=(2,0)theory 
    Lechtenfeld, Olaf; Popov, Alexander D. (Amsterdam : Elsevier B.V., 2019)
    Compactifying type A N−1 6d N=(2,0)supersymmetric CFT on a product manifold M 4 ×Σ 2 =M 3 ×S˜ 1 ×S 1 ×I either over S 1 or over S˜ 1 leads to maximally supersymmetric 5d gauge theories on M 4 ×I or on M 3 ×Σ 2 , respectively. ...
  • Dual-dual formulations for frictional contact problems in mechanics 
    Andres, Michael (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2010)
    [no abstract]
  • A Dual-Species Atom Interferometer Payload for Operation on Sounding Rockets 
    Elsen, Michael; Piest, Baptist; Adam, Fabian; Anton, Oliver; Arciszewski, Paweł; Bartosch, Wolfgang; Becker, Dennis; Bleeke, Kai; Böhm, Jonas; Boles, Sören; Döringshoff, Klaus; Guggilam, Priyanka; Hellmig, Ortwin; Imwalle, Isabell; Kanthak, Simon; Kürbis, Christian; Koch, Matthias; Lachmann, Maike Diana; Mihm, Moritz; Müntinga, Hauke; Nepal, Ayush Mani; Oberschulte, Tim; Ohr, Peter; Papakonstantinou, Alexandros; Prat, Arnau; Reichelt, Christian; Sommer, Jan; Spindeldreier, Christian; Warner, Marvin; Wendrich, Thijs; Wenzlawski, André; Blume, Holger; Braxmaier, Claus; Lüdtke, Daniel; Peters, Achim; Rasel, Ernst Maria; Sengstock, Klaus; Wicht, Andreas; Windpassinger, Patrick; Grosse, Jens (Heidelberg : Springer, 2023)
    We report on the design and the construction of a sounding rocket payload capable of performing atom interferometry with Bose-Einstein condensates of 41 K and 87 Rb. The apparatus is designed to be launched in two consecutive ...
  • Dynamic coherent beam combining based on a setup of microlens arrays 
    Prossotowicz, Maike; Heimes, Andreas; Flamm, Daniel; Jansen, Florian; Otto, Hans-Jürgen; Budnicki, Aleksander; Morgner, Uwe; Killi, Alexander (Bellingham : SPIE, 2020)
    A novel optical concept is introduced with standard components for highly efficient coherent beam combining a system of (N x N) beams. In a proof-of-principle experiment a well-defined setup with microlens arrays (MLAs) ...
  • Dynamic Optimization of Gas Transmission Networks for Storage of Renewable Energy 
    Thiedau, Jan (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)

    The dynamical scaling of the quantum Hall plateau phase transition in the frequency range 0.1-55 GHz was examined. A universal scaling function was observed, yielding a dynamical exponent 0.9 ± 0.2. The universal behavior ...

    Osborne, Tobias J.; Stiegemann, Deniz E. (Berlin ; Heidelberg : Springer, 2020)
    We describe how to introduce dynamics for the holographic states and codes introduced by Pastawski, Yoshida, Harlow and Preskill. This task requires the definition of a continuous limit of the kinematical Hilbert space ...
