  • Coulomb branches for rank 2 gauge groups in 3d N= 4 gauge theories 
    Hanany, Amihay; Sperling, Marcus (Heidelberg : Springer Verlag, 2016)
    The Coulomb branch of 3-dimensional N=4 gauge theories is the space of bare and dressed BPS monopole operators. We utilise the conformal dimension to define a fan which, upon intersection with the weight lattice of a ...
  • Coulomb crystallization of highly charged ions 
    Schmöger, L.; Versolato, O.O.; Schwarz, M.; Kohnen, M.; Windberger, A.; Piest, B.; Feuchtenbeiner, S.; Pedregosa, J.; Leopold, T.; Micke, P.; Hansen, A.K.; Baumann, T.M.; Drewsen, M.; Ullrich, J.; Schmidt, Piet O.; Crespo López-Urrutia, J.R. (Bristol : IOP Publishing Ltd., 2015)
    Sympathetic Coulomb crystallization of highly charged ions, retrapped in a cryogenic radiofrequency trap, is demonstrated by an over seven orders-of-magnitude decrease in motional temperature.
  • Counterpart of the Weyl tensor for Rarita-Schwinger type fields 
    Brandt, Friedemann (Amsterdam : Elsevier BV, 2017)
    In dimensions larger than 3 a modified field strength for Rarita-Schwinger type fields is constructed whose components are not constrained by the field equations. In supergravity theories the result provides a modified ...
  • Counting imaginary quadratic points via universal torsors 
    Derenthal, U.; Frei, C. (Cambridge : Cambridge University Press, 2014)
    A conjecture of Manin predicts the distribution of rational points on Fano varieties. We provide a framework for proofs of Manin's conjecture for del Pezzo surfaces over imaginary quadratic fields, using universal torsors. ...

    Sethubalasubramanian, Nandhavel (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2016)

  • Coupled Pb chains on Si(557): Origin of one-dimensional conductance 
    Tegenkamp, Christoph; Ohta, T.; McChesney, J.L.; Dil, H.; Rotenberg, E.; Pfnür, Herbert; Horn, K. (College Park, MD : American Physical Society, 2008)
    The Pb/Si(557) system exhibits a strong anisotropy in conductance below 78 K, with the evolution of a characteristic chain structure. Here we show, using angle-resolved photoemission, that chain ordering results in complete ...
  • The coupling flow of N = 4 super Yang-Mills theory 
    Rupprecht, Maximilian (Berlin, Heidelberg : Springer, 2022)
    We offer a novel perspective on N = 4 supersymmetric Yang-Mills (SYM) theory through the framework of the Nicolai map, a transformation of the bosonic fields that allows one to compute quantum correlators in terms of a ...
  • Coupling in concentric double quantum rings 
    Mühle, A.; Wegscheider, W.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2007)
    We designed a device consisting of two concentric quantum rings in a GaAsAlGaAs heterostructure. The outer ring is connected to leads while the inner ring is only capacitively coupled to the rest of the system. Measuring ...
  • Coupling of Finite and Boundary Elements for Singularly Nonlinear Transmission and Contact Problems 
    Gimperlein, Heiko; Stephan, Ernst P. (Berlin : De Gruyter, 2023)
    This article discusses the well-posedness and error analysis of the coupling of finite and boundary elements for interface problems in nonlinear elasticity. It concerns p-Laplacian-type Hencky materials with an unbounded ...
  • Coupling of relative intensity noise and pathlength noise to the length measurement in the optical metrology system of LISA Pathfinder 
    Wittchen, A.; et al.; LPF Collaboration (Bristol : Institute of Physics Publishing, 2017)
    LISA Pathfinder is a technology demonstration mission for the space-based gravitational wave observatory, LISA. It demonstrated that the performance requirements for the interferometric measurement of two test masses in ...
  • Coupling symmetry of quantum dot states 
    Rogge, M.C.; Harke, B.; Fricke, Christian; Hohls, Frank; Reinwald, M.; Wegscheider, W.; Haug, Rolf J. (College Park, MD : American Physical Society, 2005)
    With noninvasive methods, we investigate ground and excited states of a lateral quantum dot. Charge detection via a quantum point contact is used to map the dot dynamics in a regime where the current through the dot is too ...
  • The Covariance Metric in the Blaschke Locus 
    Dai, Xian; Eptaminitakis, Nikolas (New York, NY : Springer, 2024)
    We prove that the Blaschke locus has the structure of a finite dimensional smooth manifold away from the Teichmüller space and study its Riemannian manifold structure with respect to the covariance metric introduced by ...
  • Coxeter-Dynkin-Diagramme einiger determinantieller Raumkurvensingularitäten 
    Alpert, Christian (Hannover : Universität Hannover, 2000)
    [no abstract]
  • CPA-free amplification of sub-10 ps pulses in Ho:YLF to the mJ-level at 2 μm wavelength 
    Hinkelmann, Moritz; Schulz, Bastian; Wandt, Dieter; Morgner, Uwe; Frede, Maik; Neumann, Jörg; Kracht, Dietmar (Bellingham : SPIE, 2019)
    The generation of sub-10 ps pulses around a wavelength of 2 μm with pulse energy at millijoule-level in a compact CPA-free amplifier chain is presented. This laser source covers a broad range of pulse repetition frequencies ...
  • CPT symmetry and its violation 
    Lehnert, Ralf (Basel : MDPI AG, 2016)
    One of the most fundamental symmetries in physics is CPT invariance. This article reviews the conditions under which CPT symmetry holds by recalling two proofs of the CPT theorem: The original Lagrangian-based analysis and ...
  • Crack path comparisons of a mixed phase‐field fracture model and experiments in punctured EPDM strips 
    Fehse, Andreas; Kröger, Nils Hendrik; Mang, Katrin; Wick, Thomas (Weinheim : Wiley-VCH, 2021)
    Working on quasi-static phase-field fracture modeling in nearly incompressible solids for crack propagation is a challenging task. To avoid arising locking effects therein, a mixed form for the solid displacement equation ...

    Lachmann, M.D.; Ahlers, H.; Becker, D.; Seidel, S.T.; Wendrich, T.; Rasel, Ernst Maria; Ertmer, Wolfgang; MAIUS-Team (Bellingham, WA : SPIE - International Society for Optical Engineering, 2018)
    On 23rd of January 2017 the first Bose-Einstein Condensate (BEC) in Space was created on-board the sounding rocket mission MAIUS-1. The successful launch marks a major advancement in the effort of performing matter wave ...

  • Creation of double-well potentials in a surface-electrode trap towards a nanofriction model emulator 
    Tanaka, U.; Nakamura, M.; Hayasaka, K.; Bautista-Salvador, A.; Ospelkaus, C.; Mehlstäubler, T.E. (Philadelphia, PA : IOP Publishing, 2021)
    We demonstrate a microfabricated surface-electrode ion trap that is applicable as a nanofriction emulator and studies of many-body dynamics of interacting systems. The trap enables both single-well and double-well trapping ...

    Lange, K.; Peise, J.; Luecke, B.; Gruber, T.; Sala, A.; Polls, A.; Ertmer, Wolfgang; Julia-Diaz, B.; Santos, L.; Klempt, C. (Bristol : Institute of Physics Publishing (IOP), 2018)
    If the boundary conditions of the quantum vacuum are changed in time, quantum field theory predicts that real, observable particles can be created in the initially empty modes. Here, we realize this effect by changing the ...
