Black hole solutions of N=2, d=4 supergravity with a quantum correction, in the H-FGK formalism

Pietro Galli, Tomas Ortin, Jan Perz +1

We apply the H-FGK formalism to the study of some properties of the general class of black holes in N=2 supergravity in four dimensions that correspond to the harmonic and hyperbol…

Brane instantons and fluxes in F-theory

Massimo Bianchi, Gianluca Inverso, Luca Martucci

We study the combined effect of world-volume and background fluxes on Euclidean D3-brane instantons in F-theory compactifications. We derive an appropriate form of the fermionic ef…

On anharmonic stabilisation equations for black holes

Pietro Galli, Kevin Goldstein, Jan Perz

We investigate the stabilisation equations for sufficiently general, yet regular, extremal (supersymmetric and non-supersymmetric) and non-extremal black holes in four-dimensional…

de Sitter vacua in N = 8 supergravity and slow-roll conditions

G. Dall'Agata, G. Inverso

In this letter we discuss de Sitter vacua in maximal gauged supergravity in 4 dimensions. We show that, using the newly deformed theories introduced in arxiv:1209.0760, we can obta…

Perturbative superstrata

Stefano Giusto, Rodolfo Russo

We study a particular class of D-brane bound states in type IIB string theory (dubbed "superstrata") that describe microstates of the 5D Strominger-Vafa black hole. By using the mi…

Semiclassical equivalence of Green-Schwarz and Pure-Spinor/Hybrid formulations of superstrings in AdS(5) x S(5) and AdS(2) x S(2) x T(6)

Alessandra Cagnazzo, Dmitri Sorokin, Arkady A. Tseytlin +1

We demonstrate the equivalence between the worldsheet one-loop partition functions computed near classical string solutions in the Green-Schwarz and in the pure-spinor formulations…

D1-D5-P microstates at the cap

Stefano Giusto, Oleg Lunin, Samir D. Mathur +1

The geometries describing D1-D5-P bound states in string theory have three regions: flat asymptotics, an anti-de Sitter throat, and a 'cap' region at the bottom of the throat. We i…

Non-geometric strings, symplectic gravity and differential geometry of Lie algebroids

Ralph Blumenhagen, Andreas Deser, Erik Plauschinn +1

Based on the structure of a Lie algebroid for non-geometric fluxes in string theory, a differential-geometry calculus is developed which combines usual diffeomorphisms with so-call…

Finite Strings From Non-Chiral Mumford Forms

Marco Matone

We show that there is an infinite class of partition functions with world-sheet metric, space-time coordinates and first order systems, that correspond to volume forms on the modul…

Evidence for a family of SO(8) gauged supergravity theories

G. Dall'Agata, G. Inverso, M. Trigiante

In this note we discuss the classification of duality orbits of N = 8 gauged supergravity models. Using tensor classifiers, we show that there is a one-parameter family of inequiva…

BPS domain walls in N=4 supergravity and dual flows

Davide Cassani, Gianguido Dall'Agata, Anton F. Faedo

We establish the conditions for supersymmetric domain wall solutions to N=4 gauged supergravity in five dimensions. These read as BPS first-order equations for the warp factor and…

A bi-invariant Einstein-Hilbert action for the non-geometric string

Ralph Blumenhagen, Andreas Deser, Erik Plauschinn +1

Inspired by recent studies on string theory with non-geometric fluxes, we develop a differential geometry calculus combining usual diffeomorphisms with what we call beta-diffeomorp…

Effective perfect fluids in cosmology

Guillermo Ballesteros, Brando Bellazzini

We describe the cosmological dynamics of perfect fluids within the framework of effective field theories. The effective action is a derivative expansion whose terms are selected by…

Fermionic Wigs for BTZ Black Holes

L. G. C. Gentile, P. A. Grassi, A. Mezzalira

We compute the wig for the BTZ black hole, namely the complete non-linear solution of supergravity equations with all fermionic zero modes. We use a "gauge completion" method start…

Extending the Belavin-Knizhnik "wonderful formula" by the characterization of the Jacobian

Marco Matone

A long-standing question in string theory is to find the explicit expression of the bosonic measure, a crucial issue also in determining the superstring measure. Such a measure was…

Holomorphic Chern-Simons theory coupled to off-shell Kodaira-Spencer gravity

Stefano Giusto, Camillo Imbimbo, Dario Rosa

We construct an action for holomorphic Chern-Simons theory that couples the gauge field to off-shell gravitational backgrounds, comprising the complex structure and the (3,0)-form…

I. L. Buchbinder, N. G. Pletnev, I. B. Samsonov

We review the background field method for three-dimensional Yang-Mills and Chern-Simons models in N=2 superspace. Superfield proper time (heat kernel) techniques are developed and…

On the vacua of N = 8 gauged supergravity in 4 dimensions

G. Dall'Agata, G. Inverso
