  • Binder, Torsten; Sandmann, Angela; Sures, Bernd; Friege, Gunnar; Theyssen, Heike; Schmiemann, Philipp (Heidelberg : Springer Verlag, 2019)
    Background: Increasingly, high dropout rates in science courses at colleges and universities have led to discussions of causes and potential support measures of students. Students’ prior knowledge is repeatedly mentioned ...
  • Vetrugno, D.; Karnesis, N. (Bristol : Institute of Physics Publishing, 2017)
    LISA Pathfinder is an in-flight test of the local sources of acceleration noise in LISA. The acceleration noise level in LISA Pathfinder is measured by the residual differential acceleration Δg between the two test masses ...
  • Xiao, Zhi; Lehnert, Ralf; Snow, W.M.; Xu, Rui (Bristol : Institute of Physics Publishing, 2018)
    In this report, we will give the first constraints on in-matter nonmetricity. We will show how the effective-field-theory (EFT) toolbox developed for the study of Lorentz violation (LV) can be employed for investigations ...
  • Mimic, Dajan; Jätz, Christoph; Herbst, Florian (Zug : GPPS, 2018)
    Diffusers convert kinetic flow energy into a rise in static pressure. This pressure recovery is the primary aerodynamic design objective for exhaust gas diffusers in power-generating steam and gas turbines. The total ...
  • Gebert, Florian; Wan, Yong; Wolf, Fabian; Heip, Jan C.; Schmidt, Piet O. (Bristol : IOP Publishing Ltd., 2018)

  • Kozyrev, N.; Krivonos, S.; Lechtenfeld, O.; Nersessian, A.; Sutulin, A. (Bristol : Institute of Physics Publishing, 2018)
    We extend the relation between the Witten-Dijkgraaf-Verlinde-Verlinde equation and N = 4 supersymmetric mechanics to arbitrary curved spaces. The resulting curved WDVV equation is written in terms of the third rank Codazzi ...
  • Chwalla, M.; Danzmann, Karsten; Fernández Barranco, G.; Fitzsimons, E.; Gerberding, Oliver; Heinzel, Gerhard; Killow, Christian J.; Lieser, M.; Perreur-Lloyd, M.; Robertson, D.I.; Schuster, Sönke; Schwarze, Thomas S.; Tröbs, M.; Ward, H.; Zwetz, M. (Bristol : IOP Publishing, 2016)
    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 ...
  • 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 ...
  • Musaeva, Diana; Ilyin, Vladimir K.; Geža, Vadims; Baake, Egbert (Amsterdam : Elsevier B.V., 2016)
    The paper presents the results of the numerical and physical experiments, aimed at assessing the influence of pulsed force of electromagnetic field on the melt motion and the fluid velocities. The experiment was performed ...
  • Aspelmeyer, Marcus; Brukner, Časlav; Giulini, Domenico; Milburn, Gerard (Bristol : IOP Publishing Ltd., 2017)
    The interplay between quantum theory and gravity remains one of the least explored fields of physics. The current 'focus on' collection summarises experimental and theoretical results from many of the leading groups around ...
  • Garner, Andrew J.P.; Dahlsten, Oscar C.O.; Nakata, Yoshifumi; Murao, Mio; Vedral, Vlatko (Bristol : Institute of Physics Publishing, 2013)
    Phase plays a crucial role in many quantum effects including interference. Here we lay the foundations for the study of phase in probabilistic theories more generally. Phase is normally defined in terms of complex numbers ...
  • Bargheer, Till; Caetano, João; Fleury, Thiago; Komatsu, Shota; Vieira, Pedro (College Park (Maryland) : APS American Physical Society, 2018)
    We propose an integrability setup for the computation of correlation functions of gauge-invariant operators inN ¼ 4 supersymmetric Yang-Mills theory at higher orders in the large Nc genus expansion and at any order in the ...
  • Sellner, S.; Besirli, M.; Bohman, M.; Borchert, M.J.; Harrington, J.; Higuchi, T.; Mooser, A.; Nagahama, H.; Schneider, G.; Smorra, C.; Tanaka, T.; Blaum, K.; Matsuda, Y.; Ospelkaus, C.; Quint, W.; Walz, J.; Yamazaki, Y.; Ulmer, S. (Bristol : Institute of Physics Publishing, 2017)
    Continuous monitoring of a cloud of antiprotons stored in a Penning trap for 405 days enables us to set an improved limit on the directly measured antiproton lifetime. From our measurements we extract a storage time of ...
  • Dinulovic, Dragan; Gerfer, Alexander; Haug, Martin; Kaiser, Matthias; Wurz, Marc Christopher; Rissing, Lutz (Amsterdam : Elsevier, 2015)
    This paper presents the design, fabrication, and characterization of on silicon integrated micro-transformers for high frequency power applications. This device has stable characteristic of L versus f up to frequencies ...
  • Shammout, Baraa (Hannover : Gottfried Wilhelm Leibniz Universität, 2020)
    In this work we present the design and the construction of a laser system for cooling an atomic gas of potassium 39K on the D1-Line by gray molasses technique. The seed laser is an Interference-filter-stabilized external-cavity ...
  • Mihovilovič, M.; Jin, G.; Long, E.; Zhang, Yi; Allada, K.; Sauer, P.U.; The Jefferson Lab Hall A Collaboration; et al. (Amsterdam : Elsevier B.V., 2019)
    We report on a precise measurement of double-polarization asymmetries in electron-induced breakup of He 3 proceeding to pd and ppn final states, performed in quasi-elastic kinematics at Q 2 = 0.25 ( GeV / c ) 2 for missing ...
  • Overbeck, Vincent Raphael; Maghrebi, Mohammad F.; Gorshkov, Alexey V.; Weimer, Hendrik (College Park, MD : American Physical Society, 2017)
    We analyze theoretically the many-body dynamics of a dissipative Ising model in a transverse field using a variational approach. We find that the steady-state phase diagram is substantially modified compared to its equilibrium ...
  • 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 ...
  • Brée, Carsten; Babushkin, Ihar; Morgner, Uwe; Demircan, Ayhan (American Physical Society, 2017)
    We demonstrate an up to now unrecognized and very effective mechanism which prevents filament collapse and allows persistent self-guiding propagation retaining a large portion of the optical energy on axis over unexpected ...
