  • Accidental SUSY: Enhanced bulk supersymmetry from brane back-reaction 
    Burgess, C.P.; Van Nierop, L.; Parameswaran, Susha L.; Salvio, A.; Williams, M. (Heidelberg : Springer Verlag, 2013)
    We compute how bulk loops renormalize both bulk and brane effective interactions for codimension-two branes in 6D gauged chiral supergravity, as functions of the brane tension and brane-localized flux. We do so by explicitly ...
  • Generalised geometry for string corrections 
    Coimbra, André; Minasian, Ruben; Triendl, Hagen; Waldram, Daniel (Berlin : Springer Verlag, 2014)
    We present a general formalism for incorporating the string corrections in generalised geometry, which necessitates the extension of the generalised tangent bundle. Not only are such extensions obstructed, string symmetries ...
  • Instantons and Killing spinors 
    Harland, Derek; Nölle, Christoph (Heidelberg : Springer Verlag, 2012)
    We investigate instantons on manifolds with Killing spinors and their cones. Examples of manifolds with Killing spinors include nearly Kähler 6-manifolds, nearly parallel G2-manifolds in dimension 7, Sasaki-Einstein ...
  • The N=4 effective action of type IIA supergravity compactified on SU(2)-structure manifolds 
    Danckaert, Thomas; Louis, Jan; Martinez-Pedrera, Danny; Spanjaard, Bastiaan; Triendl, Hagen (New York, NY : Springer International Publishing, 2011)
    We study compactifications of type IIA supergravity on six-dimensional manifolds with SU(2) structure and compute the low-energy effective action in terms of the non-trivial intrinsic torsion. The consistency with gauged ...
  • N=4 supersymmetric AdS(5) vacua and their moduli spaces 
    Louis, Jan; Triendl, Hagen; Zagermann, Marco (New York : Springer, 2015-10-13)
    We classify the N = 4 supersymmetric AdS(5) backgrounds that arise as solutions of five-dimensional N = 4 gauged supergravity. We express our results in terms of the allowed embedding tensor components and identify the ...
  • New actions for modified gravity and supergravity 
    Ketov, Sergey V.; Terada, T. (Heidelberg : Springer Verlag, 2013)
    We extend the f (R) gravity action by including a generic dependence upon the Weyl tensor, and further generalize it to supergravity by using the super-curvature R and super-Weyl W chiral superfields in N = 1 chiral curved ...
  • Order α′ heterotic domain walls with warped nearly Kähler geometry 
    Haupt, Alexander S.; Lechtenfeld, Olaf; Musaev, Edvard T. (New York : Springer, 2014)
    We consider (1+3)-dimensional domain wall solutions of heterotic supergravity on a six-dimensional warped nearly Kähler manifold X 6 in the presence of gravitational and gauge instantons of tanh-kink type as constructed ...
  • Supersymmetric AdS 7 and AdS 6 vacua and their consistent truncations with vector multiplets 
    Malek, E.; Samtleben, H.; Camell, V.V. (Heidelberg : Springer Verlag, 2019)
    Using exceptional field theory we construct supersymmetric warped AdS 7 vacua of massive IIA and AdS 6 vacua of IIB, as well as their consistent truncations including vector multiplets. We show that there are no consistent ...
