  • Cosmological constant, near brane behavior and singularities 
    Gautason, Fridrik Freyr; Junghans, Daniel; Zagermann, Marco (New York, NY : Springer International Publishing, 2013)
    We show that the classical cosmological constant in type II flux compactifications can be written as a sum of terms from the action of localized sources plus a specific contribution from non-trivial background fluxes. ...
  • Holographic fluctuations and the principle of minimal complexity 
    Chemissany, Wissam; Osborne, Tobias J. (Heidelberg : Springer Verlag, 2016)
    We discuss, from a quantum information perspective, recent proposals of Maldacena, Ryu, Takayanagi, van Raamsdonk, Swingle, and Susskind that spacetime is an emergent property of the quantum entanglement of an associated ...
  • The problematic backreaction of SUSY-breaking branes 
    Blaback, Johan; Danielsson, Ulf H.; Junghans, Daniel; Van Riet, Thomas; Wrase, Timm; Zagermann, Marco (New York, NY : Springer International Publishing, 2011)
    In this paper we investigate the localisation of SUSY-breaking branes which, in the smeared approximation, support specific non-BPS vacua. We show, for a wide class of boundary conditions, that there is no flux vacuum when ...
