The singular Black hole formation Magnetic monopoles. Gravity magnetic False vacuum
2014/12/9
In the first part of the thesis we study the formation of non-singular black holes in the collapse of magnetic monopoles. We employ a thin shell approximation model for a gravitating magnetic monople ...
Supergravity as Generalised Geometry I: Type II Theories
Supergravity Generalised Geometry I High Energy Physics - Theory
2011/9/30
Abstract: We reformulate ten-dimensional type II supergravity as a generalised geometrical analogue of Einstein gravity, defined by an $O(9,1)\times O(1,9)\subset O(10,10)\times\bbR^+$ structure on th...
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...
Some Aspects of Spherical Symmetric Extremal Dyonic Black Holes in 4d N=1 Supergravity
Aspects of Spherical Symmetric Extremal Dyonic Black Holes 4d N=1 Supergravity
2011/3/2
In this paper we study several aspects of extremal spherical symmetric black hole solutions

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 in 8D N=1 Supergravity
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...
On Hybrid (Topologically) Massive Supergravity in Three Dimensions
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...
Vacua of N=10 three dimensional gauged supergravity
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)}...
