  • Additivity of entropic uncertainty relations 
    Schwonnek, Rene (Wien : Verein zur Förderung des Open Access Publizierens in den Quantenwissenschaften, 2018)
    We consider the uncertainty between two pairs of local projective measurements performed on a multipartite system. We show that the optimal bound in any linear uncertainty relation, formulated in terms of the Shannon ...

    Dai, Yi; Basu, Sukanta; Maronga, Björn; de Roode, Stephan R. (Dordrecht [u.a.] : Springer Science + Business Media B.V, 2020)
    We have identified certain fundamental limitations of a mixing-length parametrization used in a popular turbulent kinetic energy-based subgrid-scale model. Replacing this parametrization with a more physically realistic ...
  • Adiabatic Ground States in Non-smooth Spacetimes 
    Sanchez Sanchez, Yafet; Schrohe, Elmar (Cham (ZG) : Springer International Publishing AG, 2023)
    Ground states are a well-known class of Hadamard states in smooth spacetimes. In this paper, we show that the ground state of the Klein–Gordon field in a non-smooth ultrastatic spacetime is an adiabatic state. The order ...

    The majority of ions and other charged particles of spectroscopic interest lack the fast, cycling transitions that are necessary for direct laser cooling. In most cases, they can still be cooled sympathetically through ...
  • All AdS(7) solutions of type II supergravity 
    Apruzzi, Fabio; Fazzi, Marco; Rosa, Dario; Tomasiello, Alessandro (New York, NY : Springer International Publishing, 2014)
    In M-theory, the only AdS(7) supersymmetric solutions are AdS(7) x S-4 and its orbifolds. In this paper, we find and classify new supersymmetric solutions of the type AdS(7) x M-3 in type II supergravity. While in IIB none ...
  • All complete intersection Calabi-Yau four-folds 
    Gray, James; Haupt, Alexander S.; Lukas, Andre (New York, NY : Springer International Publishing, 2013)
    We present an exhaustive, constructive, classification of the Calabi-Yau four-folds which can be described as complete intersections in products of projective spaces. A comprehensive list of 921,497 configuration matrices ...
