  • Busch, U.; Beckmann, B.R.; Roth, R. (Copenhagen : Munksgaard Int. Publ. Ltd.Abingdon : Taylor and Francis Ltd., 1998)
    In this paper, we provide an estimation of the seasonal distribution of strong wind and storm weather situations in an ECHAM3/T42 climate model simulation in relation to observed conditions. Observational data of the German ...
  • Hulek, Klaus; Spandaw, J.; van Geemen, B.; van Straten, D. (Berlin : Walter de Gruyter, 2001-08)
    The moduli space of (1, 3)-polarized abelian surfaces with full level-2 structure is birational to a double cover of the Barth Nieto quintic. Barth and Nieto have shown that these varieties have Calabi-Yau models Z and Y, ...
  • Alexeev, V.; Birkenhake, C.; Hulek, Klaus (Berlin : Walter de Gruyter, 2002)
    Let (C, l) be a stable curve with an involution. Following a classical construction one can define its Prym variety P, which in this case turns out to be a semiabelian group variety and usually not complete. In this paper ...
  • Belyaev, A. K.; Grosser, J.; Liévin, J.; Vaeck, N. (Basel : MDPI AG, 2002)
    We report the application of the quantum approach, which takes full account of electron translation at low collisional energies, to the charge exchange process H, D + C4+ → H+, D+ + C3+(3s; 3p; 3d). The partial and the ...
  • Tegenkamp, Christoph; Wollschläger, Joachim; Pfnür, Herbert; Meyer zu Heringdorf, Frank-J.; Horn-von Hoegen, Michael (College Park, MD : American Physical Society, 2002)
    Using spot profile analysis in low-energy electron diffraction, we have investigated vicinal Ge(100) surfaces, which were miscut by 2.7° and 5.4°, respectively, in [011] direction with respect to the surface normal. Within ...
  • Escher, Joachim; Pruss, Jan; Simonett, Gieri (Berlin : Walter de Gruyter, 2003)
    We provide existence of a unique smooth solution for a class of one- and two-phase Stefan problems with Gibbs-Thomson correction in arbitrary space dimensions. In addition, it is shown that the moving interface depends ...
  • Kramer, J.; Tegenkamp, Christoph; Pfnür, Herbert (College Park, MD : American Physical Society, 2003)
    In order to find criteria for discrimination between surface color centers at terraces and steps, and bulk color centers, the characteristic losses of these centers have been investigated by electron energy loss spectroscopy ...
  • Ernst, Wolfgang; Jonas, K.-L.; von Oeynhausen, V.; Tegenkamp, Christoph; Pfnür, Herbert (College Park, MD : American Physical Society, 2003)
    The Na-induced surface structures on Ge(100) at concentrations below 0.1 monolayer (ML) have been investigated with low-energy electron diffraction and with scanning tunneling microscopy (STM). Annealing and partial ...
  • Schulze Wischeler, Fritz (Hannover : Technische Informationsbibliothek u. UniversitätsbibliothekTechnische Informationsbibliothek u. UniversitätsbibliothekHannover, 2004)
    In dieser Arbeit wurde der Quanten-Hall-Effekt mit Hilfe von Phononen untersucht. Ziel der Arbeit war es, die thermodynamischen Eigenschaften von zweidimensionalen Elektronensystemen und Größe der Energielücken im fraktionalen ...
  • Baranov, M.A.; Dobrek, L.; Lewenstein, M. (Bristol : IOP Publishing Ltd., 2004)
    We present a detailed study of the BCS pairing transition in a trapped polarized dipolar Fermi gas. In the case of a shallow nearly spherical trap, we find a decrease in the transition temperature as a function of the trap ...
  • Aufmuth, Peter; Danzmann, Karsten (Bristol : Institute of Physics Publishing, 2005)
    The existence of gravitational radiation is a prediction of Einstein's general theory of relativity. Gravitational waves are perturbations in the curvature of spacetime caused by accelerated masses. Since the 1960s ...
  • Morgenstern, Karina; Rieder, Karl-Heinz (Bristol : IOP Publishing Ltd., 2005)
    Formation and motion of copper adatoms and addimers on Ag( 1 1 1) are investigated with low-temperature scanning tunnelling microscopy between 6 and 25 K. Adatoms move between fcc and hcp sites with a strong preference for ...
  • Schulte, T.; Drenkelforth, S.; Kruse, J.; Tiemeyer, R.; Sacha, K.; Zakrzewski, J.; Lewenstein, M.; Ertmer, Wolfgang; Arlt, J.J. (Bristol : IOP Publishing Ltd., 2006)
    Disorder plays a crucial role in many systems particularly in solid state physics. However, the disorder in a particular system cannot usually be chosen or controlled. We show that the unique control available for ultracold ...
  • Rogge, M.C.; Cavaliere, F.; Sassetti, M.; Haug, Rolf J.; Kramer, B. (Bristol : IOP Publishing Ltd., 2006)
    Experimental results for the sequential transport through a lateral quantum dot in a perpendicular magnetic field are compared with theory. Regular patterns of negative differential conductances are observed in the nonlinear ...
  • Wuttke, Sigrid; Seckmeyer, Gunther; König-Langlo, Gert (Göttingen : Copernicus, 2006-03-07)
    Spectral albedo in high resolution, from 290 to 1050 nm, has been measured at Neumayer, Antarctica, (70 390 S, 8 150 W) during the austral summer 2003/2004. At 500 nm, the spectral albedo nearly reaches unity, ...
  • Melo, Severino T.; Schick, Thomas; Schrohe, Elmar (Berlin : Walter de Gruyter, 2006-12-07)
    We study the C*-closure U of the algebra of all operators of order and class zero in Boutet de Monvel's calculus on a compact connected manifold X with boundary partial derivative X not equal phi. We find short exact ...
  • Nawrodt, Ronny; Zimmer, A.; Koettig, T.; Clausnitzer, T.; Bunkowski, A.; Kley, E.B.; Schnabel, Roman; Danzmann, Karsten; Nietzsche, S.; Vodel, W.; Tuennermann, A.; Seidel, P. (Bristol : IOP Publishing Ltd., 2007)
    We present mechanical Q-factors (quality factors) of a crystalline quartz test mass with a nano-structured surface, measured in the temperature regime from 5 to 300 K. The nano-structure was a grating with a period of 2 ...
  • Eckert, K.; Zawitkowski, L.; Leskinen, M. J.; Sanpera, A.; Lewenstein, M. (Bristol : IOP Publishing Ltd., 2007)
    We investigate magnetic properties of Mott-insulating phases of ultracold Bose and Fermi spinor gases in optical lattices. We consider in particular the F = 2 Bose gas, and the F = 3/2 and 5/2 Fermi gases. We derive effective ...

    We report the experimental realization of squeezed quantum states of light, tailored for new applications in quantum communication and metrology. Squeezed states in a broad Fourier frequency band down to 1 Hz have been ...
  • Hage, B.; Franzen, A.; DiGuglielmo, J.; Marek, P.; Fiurasek, Jaromir; Schnabel, R. (Bristol : IOP Publishing Ltd., 2007)
    Recently it was discovered that non-Gaussian decoherence processes, such as phase-diffusion, can be counteracted by purification and distillation protocols that are solely built on Gaussian operations. Here, we make use ...
