Generating Geodesic Flows and Supergravity Solutions
E. Bergshoeff, W. Chemissany, A. Ploegh +2
We consider the geodesic motion on the symmetric moduli spaces that arise after timelike and spacelike reductions of supergravity theories. The geodesics correspond to timelike res…
Q-instantons
E. A. Bergshoeff, J. Hartong, A. Ploegh +1
We construct the half-supersymmetric instanton solutions that are electric-magnetically dual to the recently discussed half-supersymmetric Q7-branes. We call these instantons `Q-in…
Pseudo-supersymmetry and a Tale of Alternate Realities
E. A. Bergshoeff, J. Hartong, A. Ploegh +2
We discuss how all variant 10d and 11d maximal supergravities, including star supergravities and supergravities in different signatures, can be obtained as different real slices of…
Scaling cosmologies, geodesic motion and pseudo-susy
Wissam Chemissany, André ploegh, Thomas Van Riet
One-parameter solutions in supergravity carried by scalars and a metric trace out curves on the scalar manifold. In ungauged supergravity these curves describe a geodesic motion. I…
Dynamics of Generalized Assisted Inflation
Jelle Hartong, André Ploegh, Thomas Van Riet +1
We study the dynamics of multiple scalar fields and a barotropic fluid in an FLRW-universe. The scalar potential is a sum of exponentials. All critical points are constructed and t…
Non-Extremal D-instantons and the AdS/CFT Correspondence
E. Bergshoeff, A. Collinucci, A. Ploegh +2
We investigate non-extremal D-instantons in an asymptotically background and the role they play in the correspondence. We find that the hologra…
