  • T-duality without isometry via extended gauge symmetries of 2D sigma models 
    Chatzistavrakidis, Athanasios; Deser, Andreas; Jonke, Larisa (New York : Springer, 2016)
    Target space duality is one of the most profound properties of string theory. However it customarily requires that the background fields satisfy certain invariance conditions in order to perform it consistently; for instance ...
  • Tail expansions for random record distributions 
    Grübel, Rudolf; Von Öhsen, Niklas (Cambridge : Cambridge University Press, 2001)
    The random record distribution ν associated with a probability distribution μ can be written as a convolution series, ν = Σn=1∞(n + 1)-1μ(Black star)n. Various authors have obtained results on the behaviour of the tails ...

    Recent developments in quantum technology have resulted in a new generation of sensors for measuring inertial quantities, such as acceleration and rotation. These sensors can exhibit unprecedented sensitivity and accuracy ...
  • Teleparallel Newton-Cartan gravity 
    Schwartz, Philip K. (Bristol : IOP Publ., 2023)
    We discuss a teleparallel version of Newton-Cartan gravity. This theory arises as a formal large-speed-of-light limit of the teleparallel equivalent of general relativity (TEGR). Thus, it provides a geometric formulation ...

    Karow, Malte (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2013)
    [no abstract]
  • Temperature dependence of the band gap of 28Si:P at very low temperatures measured via time-resolved optical spectroscopy 
    Sauter, E.; Abrosimov, N.V.; Hübner, J.; Oestreich, M. (College Park, MD : APS, 2023)
    We measure the temperature dependence of the indirect band gap of isotopically purified 28Si:P in the regime from 0.1 K to 3 K by high-resolution absorption spectroscopy of the donor bound exciton transition. The measurements ...
  • Temperature measurement with lanthanide doped nanocrystals 
    Thiem, Jonas (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2022)
    Temperature is one of the fundamental physical state variables through out most scientific and technological applications. However, measuring temperature is not always as straight forward as it may seem, especially if ...
  • Temperature-dependent accommodation of two lattices of largely different size during growth 
    Sprodowski, Carsten; Morgenstern, Karina (Basel : MDPI AG, 2019)
    If a material grows on another material with a largely different lattice constant, which of the two adapts for an energetically favorable growth? To tackle this question, we investigate the growth of Ag on Cu(111) by ...
  • Temperature-dependent broadening of coherent current peaks in InAs double quantum dots 
    Dani, Olfa; Hussein, Robert; Bayer, Johannes C.; Kohler, Sigmund; Haug, Rolf J. (London : Springer Nature, 2022)
    Quantum systems as used for quantum computation or quantum sensing are nowadays often realized in solid state devices as e.g. complex Josephson circuits or coupled quantum-dot systems. Condensed matter as an environment ...
