Journal of High Energy Physics, 2001 We find the supergravity solution sourced by a supertube: a (1/4)-supersymmetric D0-charged IIA superstring that has been blown up to a cylindrical D2-brane by angular momentum. The supergravity solution captures all essential features of the supertube, including the D2-dipole moment and an upper bound on the angular momentum: violation of this bound ...

, 2023 A large class of supergravities in diverse dimensions are surveyed. This includes maximal supergravities, their general gaugings in the framework of embedding tensor formalism, supergravities with less than maximal supersymmetry, their matter couplings and general gaugings.

Journal of High Energy Physics, 2023 Abstract We construct two-dimensional supergravity theories endowed with a positive cosmological constant, that admit de Sitter vacua. We consider the cases of $$ \mathcal{N} $$ N = 1 as well as $$ \mathcal{N} $$ N = 2 supersymmetry, and couple the supergravity ...

Lifshitz solutions in supergravity and string theory [PDF]
, 2010 We derive Lifshitz configurations in string theory for general dynamical exponents z \geq 1. We begin by obtaining simple Li x Omega solutions to supergravities in diverse dimensions, with Omega a compact constant curvature manifold.

Physics Letters B, 1999 In the context of quintessence, the concept of tracking solutions allows to address the fine-tuning and coincidence problems. When the field is on tracks today, one has $Q\approx m_{\rm Pl}$ demonstrating that, generically, any realistic model of quintessence must be based on supergravity.

Two-centered magical charge orbits [PDF]
, 2011 We determine the two-centered generic charge orbits of magical N = 2 and maximal N = 8 supergravity theories in four dimensions. These orbits are classified by seven U-duality invariant polynomials, which group together into four invariants under the ...

Physics Letters B, 1986 Abstract The anomaly of the supercurrent of an abelian vector multiplet interacting with external supergravity is considered, and it is shown that it is equivalent to a gravitational anomaly. The local counterterms that reinstate the conservation of the supercurrent are exhibited.
