Supergravity backgrounds of the η-deformed AdS2 × S2 × T6 and AdS5 × S5 superstrings [PDF]
We construct supergravity backgrounds for the integrable η-deformations of the AdS2 × S2 × T6 and AdS5 × S5 superstring sigma models. The η-deformation is governed by an R-matrix that solves the non-split modified classical Yang-Baxter equation on the ...

Supersymmetric RG flows and Janus from type II orbifold compactification
We study holographic RG flow solutions within four-dimensional $$N=4$$ N = 4 gauged supergravity obtained from type IIA and IIB string theories compactified on $$T^6/\mathbb {Z}_2\times \mathbb {Z}_2$$ T 6 / Z 2 × Z 2 orbifold with gauge, geometric and ...

Warped AdS6 × S2 in Type IIB supergravity II: global solutions and five-brane webs [PDF]
A bstractMotivated by the construction of holographic duals to five-dimensional superconformal quantum field theories, we obtain global solutions to Type IIB supergravity invariant under the superalgebra F (4) on a space-time of the form AdS6 × S2 warped

Classical Yang-Baxter equation from β-supergravity [PDF]
A bstractYang-Baxter deformations of superstring σ-models have recently inspired a supergravity solution generating technique. Using the open/closed string map and a Killing bi-vector as a deformation parameter, new solutions can be built, such that the (

Supergravity Solutions for BI Dyons [PDF]
We construct partially localized supergravity counterpart solutions to the 1/2 supersymmetric non-threshold and the 1/4 supersymmetric threshold bound state BI dyons in the D3-brane Dirac-Born-Infeld theory.

Kappa-symmetry of superstring sigma model and generalized 10d supergravity equations [PDF]
A bstractWe determine the constraints imposed on the 10d target superspace geometry by the requirement of classical kappa-symmetry of the Green-Schwarz superstring.

Quintessence with two energy scales [PDF]
We study quintessence models using low energy supergravity inspired from string theory. We consider effective supergravity with two scales m_S, the string scale, and m_PL, the Planck scale and show that quintessence naturally arises from a supersymmetry ...

Supersymmetric AdS$$_2\times \Sigma _2$$ 2×Σ2 solutions from tri-sasakian truncation
A class of $$\mathrm{AdS}_2\times \Sigma _2$$ AdS2×Σ2 , with $$\Sigma _2$$ Σ2 being a two-sphere or a hyperbolic space, solutions within four-dimensional $$N=4$$ N=4 gauged supergravity coupled to three-vector multiplets with dyonic gauging is identified.

Five-loop four-point integrand of N=8 supergravity as a generalized double copy [PDF]
We use the recently developed generalized double-copy procedure to construct an integrand for the fiveloop four-point amplitude of N = 8 supergravity.
