  • Nitsche, Thomas; Geib, Tobias; Stahl, Christoph; Lorz, Lennart; Cedzich, Christopher; Barkhofen, Sonja; Werner, Reinhard F; Silberhorn, Christine (Bristol : Institute of Physics Publishing, 2019)
    We study topological phenomena of quantum walks by implementing a novel protocol that extends the range of accessible properties to the eigenvalues of the walk operator. To this end, we experimentally realise for the first ...
  • Marquardt, Jürgen; Wendel, Ralf (Berlin : De Gruyter, 1996)
    A modal analysis of a ridged circular waveguide is presented. The method of Kühn [1] is used to find suitable expressions for the vectorpotentials, wherefore the ridged waveguide is intersected into a lot of regions. With ...
  • Krumm, M.; Barnum, H.; Barrett, J.; Müller, M.P. (Bristol : Institute of Physics Publishing, 2017)
    Despite its enormous empirical success, the formalism of quantum theory still raises fundamental questions: why is nature described in terms of complex Hilbert spaces, and what modifications of it could we reasonably expect ...
