Higher-dimensional Rotating Charged Black Holes

Marco M. Caldarelli, Roberto Emparan, Bert Van Pol

Using the blackfold approach, we study new classes of higher-dimensional rotating black holes with electric charges and string dipoles, in theories of gravity coupled to a 2-form o…

Chronology protection and the stringy exclusion principle

Joris Raeymaekers, Dieter Van den Bleeken, Bert Vercnocke

We construct a family of supersymmetric solutions to AdS supergravity in three dimensions, that correspond to type IIB seven branes wrapped on an internal S3xT4. These solutions ar…

String Junctions and Holographic Interfaces

Marco Chiodaroli, Michael Gutperle, Ling-Yan Hung +1

In this paper we study half-BPS type IIB supergravity solutions with multiple asymptotic regions, where is either or . These solutions…

Rigid D6-branes on T6/[Z(2)xZ(2M)xOmegaR] with discrete torsion

Stefan Forste, Gabriele Honecker

We give a complete classification of T6/[Z(2)xZ(2M)xOmegaR] orientifolds on factorisable tori and rigid D6-branes on them. The analysis includes the supersymmetry, RR tadpole cance…

On Vector Meson Masses in a Holographic SQCD

Aldo L. Cotrone, Anatoly Dymarsky, Stanislav Kuperstein

We study probe flavor branes supersymmetrically embedded in the Klebanov-Strassler background. The embedding is controlled by a single complex parameter mu related to the quark mas…

Bound state transformation walls

Evgeny Andriyash, Frederik Denef, Daniel L. Jafferis +1

In four dimensional N=2 supergravity theories, BPS bound states near marginal stability are described by configurations of widely separated constituents with nearly parallel centra…

Superconformal Symmetry, NMSSM, and Inflation

Sergio Ferrara, Renata Kallosh, Andrei Linde +2

We identify a particularly simple class of supergravity models describing superconformal coupling of matter to supergravity. In these models, which we call the canonical superconfo…

Wall-crossing from supersymmetric galaxies

Evgeny Andriyash, Frederik Denef, Daniel L. Jafferis +1

We give an elementary physical derivation of the Kontsevich-Soibelman wall crossing formula, valid for any theory with a 4d N=2 supergravity description. Our argument leads to a sl…

Lectures on Generalized Complex Geometry for Physicists

Paul Koerber

In these lectures we review Generalized Complex Geometry and discuss two main applications to string theory: the description of supersymmetric flux compactifications and the supers…

Jordan Frame Supergravity and Inflation in NMSSM

Sergio Ferrara, Renata Kallosh, Andrei Linde +2

We present a complete explicit N=1, d=4 supergravity action in an arbitrary Jordan frame with non-minimal scalar-curvature coupling of the form . The action is de…

Universal de Sitter solutions at tree-level

Ulf H. Danielsson, Paul Koerber, Thomas Van Riet

Type IIA string theory compactified on SU(3)-structure manifolds with orientifolds allows for classical de Sitter solutions in four dimensions. In this paper we investigate these s…

Field Representations of Vector Supersymmetry

Roberto Casalbuoni, Federico Elmetti, Simon Knapen +1

We study some field representations of vector supersymmetry with superspin Y=0 and Y=1/2 and nonvanishing central charges. For Y=0, we present two multiplets composed of four spino…

Generalized gaugings and the field-antifield formalism

Frederik Coomans, Jan De Rydt, Antoine Van Proeyen

We discuss the algebra of general gauge theories that are described by the embedding tensor formalism. We compare the gauge transformations dependent and independent of an invarian…

A landscape of non-supersymmetric AdS vacua on coset manifolds

Paul Koerber, Simon Kors

We construct new families of non-supersymmetric sourceless type IIA AdS4 vacua on those coset manifolds that also admit supersymmetric solutions. We investigate the spectrum of lef…
