  • Heterotic compactifications on nearly Kahler manifolds 
    Lechtenfeld, Olaf; Noelle, Christoph; Popov, Alexander D. (New York, NY : Springer International Publishing, 2010)
    We consider compactifications of heterotic supergravity on anti-de Sitter space, with a six-dimensional nearly Kahler manifold as the internal space. Completing the model proposed by Frey and Lippert [10] with the particular ...
  • Heterotic G(2)-manifold compactifications with fluxes and fermionic condensates 
    Gemmer, Karl-Philip; Lechtenfeld, Olaf (New York, NY : Springer International Publishing, 2013)
    We consider flux compactifications of heterotic string theory in the presence of fermionic condensates on M-1,M-2 x X-7 with both factors carrying a Killing spinor. In other words, M-1,M-2 is either de Sitter, anti-de ...
  • Integrated Optical Deformation Measurement with TIR Prism Rods 
    Wolf, Alexander (Basel : MDPI, 2023)
    In this paper, a novel optical measurement principle for deformation, especially torsion, is presented. A laser beam is guided via total internal reflection (TIR) in a prism rod. Every single reflection causes an increasing ...
  • Steel fiber reinforced RC beams in pure torsion—Load-bearing behavior and modified space truss model 
    Oettel, Vincent (Malden, Mass. : Wiley, 2022)
    Investigations on steel fiber reinforced concrete (RC) beams in torsion show, that the steel fibers positively influence the torsional load-bearing behavior. Since a systematic evaluation of the previously known test results ...
