Classification of Supersymmetric Flux Vacua in M Theory
Klaus Behrndt, Mirjam Cvetic, Tao Liu
We present a comprehensive classification of supersymmetric vacua of M-theory compactification on seven-dimensional manifolds with general four-form fluxes. We analyze the cases wh…
General Type IIB Fluxes with SU(3) Structures
Klaus Behrndt, Mirjam Cvetic, Peng Gao
A supersymmetric vacuum has to obey a set of constraints on fluxes as well as first order differential equations defined by the G-structures of the internal manifold. We solve thes…
General N = 1 Supersymmetric Fluxes in Massive Type IIA String Theory
Klaus Behrndt, Mirjam Cvetic
We study conditions on general fluxes of massive Type IIA supergravity that lead to four-dimensional backgrounds with N = 1 supersymmetry. We derive these conditions in the case of…
General N = 1 Supersymmetric Flux Vacua of (Massive) Type IIA String Theory
Klaus Behrndt, Mirjam Cvetic
We derive conditions for the existence of four-dimensional \N=1 supersymmetric flux vacua of massive type IIA string theory with general supergravity fluxes turned on. For an SU(3)…
Black holes in Goedel-type universes with a cosmological constant
Klaus Behrndt, Dietmar Klemm
We discuss supersymmetric black holes embedded in a Goedel-type universe with cosmological constant in five dimensions. The spacetime is a fibration over a four-dimensional Kaehler…
De Sitter vacua from N=2 gauged supergravity
Klaus Behrndt, Swapna Mahapatra
Typical de Sitter (dS) vacua of gauged supergravity correspond to saddle points of the potential and often the unstable mode runs into a singularity. We explore the possibility to…
