Spectral Geometry of Black Holes in 4D Gauged Supergravity

open access: yesUniverse, 2021
In this work we show that the area of the event horizon of the Chong–Cvetic–Lu–Pope black hole can be reconstructed in terms of the spectra of the Laplacian on the event horizon.

False Vacuum Chaotic Inflation: The New Paradigm? [PDF]

open access: yes, 1994
Recent work is reported on inflation model building in the context of supergravity and superstrings, with special emphasis on False Vacuum (`Hybrid') Chaotic Inflation.

Holographic RG flows in $$N=4$$ N=4 SCFTs from half-maximal gauged supergravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
We study four-dimensional $$N=4$$ N=4 gauged supergravity coupled to six vector multiplets with semisimple gauge groups $$SO(4)\times SO(4)$$ SO(4)×SO(4) , $$SO(3,1)\times SO(3,1)$$ SO(3,1)×SO(3,1) and $$SO(4)\times SO(3,1)$$ SO(4)×SO(3,1) . All of these

Novel Free Differential Algebras for Supergravity

open access: yesUniverse, 2023
We develop the theory of Free Integro-Differential Algebras (FIDA) extending the powerful technique of Free Differential Algebras constructed by D. Sullivan. We extend the analysis beyond the superforms to integral- and pseudo-forms used in supergeometry.

Macroscopic strings as heavy quarks: Large-N gauge theory and anti-de Sitter supergravity [PDF]

open access: yes, 1998
. We study some aspects of Maldacena's large-N correspondence between ${\cal N}=4$ superconformal gauge theory on the D3-brane and maximal supergravity on AdS$_5 \times S_5$ by introducing macroscopic strings as heavy (anti-) quark probes.

Holographic microstate counting for AdS4 black holes in massive IIA supergravity [PDF]

open access: yesJournal of High Energy Physics, 2017
We derive the Bekenstein-Hawking entropy for a class of BPS black holes in the massive type IIA supergravity background AdS4 × S6 from a microscopic counting of supersymmetric ground states in a holographically dual field theory.

N=2 Chiral Supergravity in (10 + 2)-Dimensions As Consistent Background for Super (2 + 2)-Brane [PDF]

open access: yes, 1997
We present a theory of N=2 chiral supergravity in (10+2)-dimensions. This formulation is similar to N=1 supergravity presented recently using null-vectors in 12D.

Two-dimensional SCFTs from matter-coupled $$7D~N=2$$ 7DN=2 gauged supergravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We study supersymmetric $$AdS_3\times M^4$$ AdS3×M4 solutions of $$N=2$$ N=2 gauged supergravity in seven dimensions coupled to three vector multiplets with $$SO(4)\sim SO(3)\times SO(3)$$ SO(4)∼SO(3)×SO(3) gauge group and $$M^4$$ M4 being a four ...

On QCD_2 from supergravity and mass gaps in QCD [PDF]

open access: yes, 1999
As a test of the conjectured QCD/supergravity duality, we consider mass gaps in the supergravity construction of QCD_2. We find a mass gap in the dual field theory both when using non-rotating and rotating black D2-branes as backgrounds in the ...

N=31 is not IIB [PDF]

open access: yes, 2006
We adapt the spinorial geometry method to investigate supergravity backgrounds with near maximal number of supersymmetries. We then apply the formalism to show that the IIB supergravity backgrounds with 31 supersymmetries preserve an additional ...
