On the Thermodynamics of Goedel Black Holes
Dietmar Klemm, Luciano Vanzo
After a brief review of Goedel-type universes in string theory, we discuss some intriguing properties of black holes immersed in such backgrounds. Among these are the upper bound o…
Chronology Protection in anti-de Sitter
Marco M. Caldarelli, Dietmar Klemm, Pedro J. Silva
We consider 1/2 BPS excitations of AdS(5)xS(5) geometries in type IIB string theory that can be mapped into free fermion configurations according to the prescription of Lin, Lunin…
Quantum Polarization of D4-branes
Belkis Cabrera Palmer, Donald Marolf, Pedro J. Silva
The low energy effective field theory of type II D4-branes coupled to bulk supergravity fields is used to investigate {\it quantum} effects for D4-branes in the D0 supergravity bac…
Some Conjectures on the Limit of Infinite Higgs Mass
Ruggero Ferrari, Marco Picariello, Andrea Quadri
We consider a possible field theory candidate for the electroweak SU(2) x U(1) model where the limit of infinitely sharp Higgs potential is performed. We show that it is possible t…
Physical Unitarity for Massive Non-abelian Gauge Theories in the Landau Gauge: Stueckelberg and Higgs
Ruggero Ferrari, Andrea Quadri
We discuss the problem of unitarity for Yang-Mills theory in the Landau gauge with a mass term a la Stueckelberg. We assume that the theory (non-renormalizable) makes sense in some…
Giant gravitons in AdS/CFT (I): matrix model and back reaction
Marco M. Caldarelli, Pedro J. Silva
In this article we study giant gravitons in the framework of AdS/CFT correspondence. First, we show how to describe these configurations in the CFT side using a matrix model. In th…
Aspects of Quantum Gravity in de Sitter Spaces
Dietmar Klemm, Luciano Vanzo
In these lectures we give a review of recent attempts to understand quantum gravity on de Sitter spaces. In particular, we discuss the holographic correspondence between de Sitter…
More on BPS solutions of N=2, D=4 gauged supergravity
Sergio L. Cacciatori, Marco M. Caldarelli, Dietmar Klemm +1
We deepen and refine the classification of supersymmetric solutions to N=2, D=4 gauged supergravity obtained in a previous paper. In the case where the Killing vector constructed f…
Integrable Noncommutative Sine-Gordon Model
Olaf Lechtenfeld, Liuba Mazzanti, Silvia Penati +2
Requiring an infinite number of conserved local charges or the existence of an underlying linear system does not uniquely determine the Moyal deformation of 1+1 dimensional integra…
Quantization of N=1 chiral/nonminimal (CNM) scalar multiplets and supersymmetric Yang-Mills theories
Gabriele Tartaglino-Mazzucchelli
We give the superfield quantization of chiral/nonminimal (CNM) scalar multiplets defined by pairs of N=1 chiral and complex linear scalar superfields kinematically coupled. In the…
Vanishing Perturbative Vacuum Energy in Non-Supersymmetric Orientifolds
Carlo Angelantonj, Matteo Cardella
We present a novel source for supersymmetry breaking in orientifold models, and show that it gives a vanishing contribution to the vacuum energy at genus zero and three-half. We al…
Multi giant graviton systems, SUSY breaking and CFT
Marco M. Caldarelli, Pedro J. Silva
In this article, we describe giant gravitons in AdS_5 x S^5 moving along generic trajectories in AdS_5. The giant graviton dynamics is solved by proving that the D3-brane effective…
Nonanticommutative superspace and N= 1/2 WZ model
M. T. Grisaru, S. Penati, A. Romagnoni
In these proceedings we review the main results concerning superspace geometries with nonanticommutative spinorial variables and field theories formulated on them. In particular, w…
Black holes in Goedel-type universes with a cosmological constant
Klaus Behrndt, Dietmar Klemm
We discuss supersymmetric black holes embedded in a Goedel-type universe with cosmological constant in five dimensions. The spacetime is a fibration over a four-dimensional Kaehler…
