Supersymmetric AdS(4) compactifications of IIA supergravity

We derive necessary and sufficient conditions for N=1 compactifications of (massive) IIA supergravity to AdS(4) in the language of SU(3) structures. We find new solutions characterized by constant…

M-theory on eight-manifolds revisited: Script N = 1 supersymmetry and generalized Spin(7) structures
- D. Tsimpis
- Mathematics
- 4 November 2005
The requirement of = 1 supersymmetry for M-theory backgrounds of the form of a warped product × wX, where X is an eight-manifold and is three-dimensional Minkowski or AdS space, implies the existence…
Generalized non-supersymmetric flux vacua

- 29 July 2008
We discuss a novel strategy to construct 4D = 0 stable flux vacua of type II string theory, based on the existence of BPS bounds for probe D-branes in some of these backgrounds. In particular, we…
Spinorial cohomology and maximally supersymmetric theories
- M. Cederwall, B. Nilsson, D. Tsimpis
- Physics
- 8 October 2001
Fields in supersymmetric gauge theories may be seen as elements in a spinorial cohomology. We elaborate on this subject, specialising to maximally supersymmetric theories, where the superspace…
The Structure of Maximally Supersymmetric Yang-Mills Theory: Constraining Higher-Order Corrections
- M. Cederwall, B. Nilsson, D. Tsimpis
- Mathematics
- 2 February 2001
We solve the superspace Bianchi identities for ten-dimensional supersymmetric Yang-Mills theory without imposing any kind of constraints apart from the standard conventional one. In this way we…
The effective theory of type IIA AdS4 compactifications on nilmanifolds and cosets
- C. Caviezel, P. Koerber, S. Körs, D. Lüst, D. Tsimpis, M. Zagermann
- Mathematics
- 23 June 2008
We consider string theory compactifications of the form AdS with orientifold six-planes, where is a six-dimensional compact space that is either a nilmanifold or a coset. For all known solutions of…
New supersymmetric AdS4 type II vacua
- D. Tsimpis
- Physics
- 15 June 2009
We review the supersymmetric AdS4 ×wℳ︁6 backgrounds of type IIA/IIB supergravity constructed in [1]. In type IIA the supersymmetry is 𝒩 = 2, and the six‐dimensional internal space is locally an S2…
Calabi–Yau Black Holes and (0,4) Sigma Models
- R. Minasian, G. Moore, D. Tsimpis
- Mathematics
- 30 April 1999
Abstract:When an M-theory fivebrane wraps a holomorphic surface ? in a Calabi–Yau 3-fold X the low energy dynamics is that of a black string in 5 dimensional ? =1 supergravity. The infrared dynamics…
Rigid supersymmetric theories in 4d Riemannian space

- Mathematics
- 15 March 2012
A bstractWe consider rigid supersymmetric theories in four-dimensional Riemannian spin manifolds. We build the Lagrangian directly in Euclidean signature from the outset, keeping track of potential…
