  • Q`-cohomology projective planes and Enriques surfaces in characteristic two 
    Schütt, Matthias (s.l. : Association de l'Épijournal de Geometrie Algebrique, 2019)
    We classify singular Enriques surfaces in characteristic two supporting a rank nine configuration of smooth rational curves. They come in one-dimensional families defined over the prime field, paralleling the situation in ...

  • Quantification of The Performance of CMIP6 Models for Dynamic Downscaling in The North Pacific and Northwest Pacific Oceans 
    Oh, Seok-Geun; Kim, Bong-Gwan; Cho, Yang-Ki; Son, Seok-Woo (Berlin ; Heidelberg [u.a.] : Springer, 2023)
    Selecting a reliable global climate model as the driving forcing in simulations with dynamic downscaling is critical for obtaining a reliable regional ocean climate. With respect to their accuracy in providing physical ...
  • Quantifizierung optischer Systeme für die optische Tomographie 
    Lorbeer, Raoul-Amadeus (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2012)
    [no abstract]
  • Quantitative Analyse der Auflösungsbegrenzung eines atomaren Gyroskops 
    Gilowski, Michael (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2010)
    [no abstract]
  • Quantization conditions for the periodic Toda chain: Inadequacy of Bethe ansatz methods 
    Fowler, Michael; Frahm, Holger (College Park (Maryland) : American Physical Society, 1989)
    Gutzwiller has developed a scheme for determining the energy levels of a finite quantum Toda lattice. We present a numerical analysis using his method and calculate low-lying energy levels for some small lattices. We check ...
  • Quantized current source with mesoscopic feedback 
    Fricke, Lukas; Hohls, Frank; Ubbelohde, Niels; Kaestner, Bernd; Kashcheyevs, Vyacheslavs; Leicht, Christoph; Mirovsky, Philipp; Pierz, Klaus; Schumacher, Hans W.; Haug, Rolf J. (College Park, MD : American Physical Society, 2011)
    We study a mesoscopic circuit of two quantized current sources, realized by nonadiabatic single-electron pumps connected in series with a small micron-sized island in between. We find that quantum transport through the ...
  • Quantum Algorithmic Readout in Multi-Ion Clocks 
    Schulte, M.; Lörch, N.; Leroux, I.D.; Schmidt, Piet O.; Hammerer, K. (College Park, MD : American Physical Society, 2016)
    Optical clocks based on ensembles of trapped ions promise record frequency accuracy with good short-term stability. Most suitable ion species lack closed transitions, so the clock signal must be read out indirectly by ...
  • The quantum angular Calogero-Moser model 
    Feigin, Mikhail; Lechtenfeld, Olaf; Polychronakos, Alexios P. (New York, NY : Springer International Publishing, 2013)
    The rational Calogero-Moser model of n one-dimensional quantum particles with inverse-square pairwise interactions (in a confining harmonic potential) is reduced along the radial coordinate of R-n to the 'angular Calogero-Moser ...
  • Quantum battles in attoscience: tunnelling 
    Hofmann, Cornelia; Bray, Alexander; Koch, Werner; Ni, Hongcheng; Shvetsov-Shilovski, Nikolay I. (Berlin ; Heidelberg : Springer, 2021)
    Abstract: What is the nature of tunnelling? This yet unanswered question is as pertinent today as it was at the dawn of quantum mechanics. This article presents a cross section of current perspectives on the interpretation, ...
  • Quantum Computing with Spatially Delocalized Qubits 
    Mompart, J.; Eckert, K.; Ertmer, Wolfgang; Birkl, G.; Lewenstein, M. (American Physical Society, 2003)
    We analyze the operation of quantum gates for neutral atoms with qubits that are delocalized in space, i.e., the computational basis states are defined by the presence of a neutral atom in the ground state of one out of ...
  • Quantum confinement effects in Si/Ge heterostructures with spatially ordered arrays of self-assembled quantum dots 
    Agafonov, Oleksiy B.; Dais, Christian; Grützmacher, Detlev; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2010)
    Magnetotunneling spectroscopy was employed to probe the confinement in vertical Si/Ge double-barrier resonant tunneling diodes with regularly distributed Ge quantum dots. Their current-voltage characteristics reveal a ...
  • Quantum control of optomechanical systems 
    Hofer, Sebastian (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2015)
    [no abstract]
  • Quantum corrections in string compactifications on SU(3) structure geometries 
    Graña, Mariana; Louis, Jan; Theis, Ulrich; Waldram, Daniel (New York : Springer, 2015)
    We investigate quantum corrections to the classical four-dimensional low-energy effective action of type II string theory compactified on SU(3) structure geometries. Various methods previously developed for Calabi-Yau ...
  • Quantum correlations and quantum key distribution 
    Franz, Torsten (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2013)

    Werner, A.H.; Franz, T.; Werner, R.F. (College Park, MD : American Physical Society, 2009)
    We propose a quantum key distribution protocol based on a quantum retrodiction protocol, known as the Mean King problem. The protocol uses a two way quantum channel. We show security against coherent attacks in a ...
  • Quantum degenerate mixtures of 23Na-39K and coherent transfer paths in NaK molecules 
    Schulze, Torben Alexander (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    The discovery and development of methods to cool, trap and manipulate atomic ensembles have generated a revolution in atomic physics, culminating in the ever expanding research field of ultra-cold matter through the ...
  • Quantum dot device tunable from single to triple dot system 
    Rogge, M.C.; Pierz, Klaus; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2013)
    We present a lateral quantum dot device which has a tunable number of quantum dots. Depending on easily tunable gate voltages, one, two or three quantum dots are found. They are investigated in transport and charge detection. ...
