Towards Loop Quantum Supergravity (LQSG)
Loop Quantum Supergravity General Relativity and Quantum Cosmology
2011/7/27
Abstract: Should nature be supersymmetric, then it will be described by Quantum Supergravity at least in some energy regimes. The currently most advanced description of Quantum Supergravity and beyond...
The Boundary Multiplet of N=4 SU(2)xU(1) Gauged Supergravity on Asymptotically-AdS_5
The Boundary Multiplet Gauged Supergravity
2010/12/23
We consider N=4 SU(2)xU(1) gauged supergravity on asymptotically-AdS_5 backgrounds. By a near-boundary analysis we determine the boundary-dominant components of the bulk fields from their partially g...

Intersecting Black Attractors 8D N=1 Supergravity
2010/12/23
We study intersecting extremal black attractors in non chiral 8D N=1 supergravity with moduli space ((SO(2,N))/(SO(2)\times SO(N)))\times SO(1,1) and work out explicitly the attractor mechanism for va...
Homogeneous heterotic supergravity solutions with linear dilaton
Homogeneous heterotic supergravity solutions linear dilaton
2010/12/23
I construct solutions to the heterotic supergravity BPS-equations on products of Minkowski space with a non-symmetric coset. All of the bosonic fields are homogeneous and non-vanishing, the dilaton be...
A spectral action associated with an Einstein-Cartan formulation of supergravity is proposed. To construct this action we make use of the Seeley-DeWitt coefficients in a Riemann-Cartan space. For con...

Massive Supergravity Three Dimensions
2010/12/24
A class of hybrid (topologically) massive off-shell supergravities coupled to an on-shell matter scalar multiplet was recently constructed. The auxiliary field in the off-shell multiplet is dynamical ...
We describe a way to construct supergravity models with an arbitrary inflaton potential V ({\phi}) and show that all other scalar fields in this class of models can be stabilized at the inflationary t...
On KLT and SYM-supergravity relations from 5-point 1-loop amplitudes
KLT SYM-supergravity relations 5-point 1-loop amplitudes
2010/12/23
We derive a new non-singular tree-level KLT relation for the $n=5$-point amplitudes, with manifest $2(n-2)!$ symmetry, using information from one-loop amplitudes and IR divergences, and speculate how...
Single-charge rotating black holes in four-dimensional gauged supergravity
Single-charge rotating black holes four-dimensional gauged supergravity
2010/12/23
We consider four-dimensional U(1)^4 gauged supergravity, and obtain asymptotically AdS_4, non-extremal, charged, rotating black holes with one non-zero U(1) charge. The thermodynamic quantities are co...

p-wave Holographic Superconductors five-dimensional gauged Supergravity
2010/12/23
We explore five-dimensional ${\cal N}=4$ $SU(2)\times U(1)$ and ${\cal N}=8$ SO(6) gauged supergravities as frameworks for condensed matter applications. These theories contain charged (dilatonic) bl...
We characterise the one-loop amplitudes for N=6 and N=4 supergravity in four dimensions. For N=6 we find that the one-loop n-point amplitudes can be expanded in terms of scalar box and triangle funct...

N=10 three dimensional gauged supergravity
2010/12/24
We study scalar potentials and the corresponding vacua of $N=10$ three dimensional gauged supergravity. The theory contains 32 scalar fields parametrizing the exceptional coset space $\frac{E_{6(-14)}...

Cosmological Solutions Supergravity
2010/12/23
We construct new non-stationary cosmological solutions to five-dimensional minimal supergravity that don't have any tri-holomorphic U(1) isometries. Our new solutions, in part, contain some of the pre...

2010/12/24
In this article, we explore the holographic Q-picture description for the charged rotating black holes in the five-dimensional minimal supergravity. The central charge in the Q-picture depends only o...

Bonus Relations N=8 Supergravity Tree Amplitudes
2010/12/24
We study the application of non-trivial relations between gravity tree amplitudes, the bonus relations, to all tree-level amplitudes in N=8 supergravity. We show that the relations can be used to sim...
