This project is based on an exciting recent finding of the visiting professor on the existence of supersymmetric solitons, for certain boundary conditions, in the Einstein-Maxwell-AdS theory in four and five dimensions [1]. This indicates the existence of new ground states of quantum gravity defined by M-theory and type IIB supergravity.The project intends to characterize these new soluti…
This proposal puts together specialists in various areas of string theory and quantum field theory and their applications in order to analyze and apply various aspects of gauge/gravity duality. This duality and its applications are one of the most important and active areas of research in theoretical physics, and we are fortunate that São Paulo is emerging as the leading center for it not…
This project intends to bring together a strong team of researchers to tackle two of the most important problems of theoretical physics. Namely, the description of strongly coupled phenomena and of quantum gravity. The strategy to be used is promising and fascinating, that is, the use of holographic duality. Holography is a precise mathematical tool that is realized through the AdS/CFT di…
The goal of this proposal is to group together specialists in quantum field theory and string theory to analyse several aspects of the gauge/gravity duality. This is one of most active areas of theoretical physics world wide and São Paulo has several actives researchers in the area. We must contrive ways to get together the researchers in this area in order to take advantage of their expe…

The AdS/CFT correspondence and its generalization, gauge/gravity duality, relates holographically a gravitational theory in a background spacetime to a field theory living at the boundary of its space. But it can be applied also to cosmology, in the strong coupling gravity regime, being dual to a 3-dimensional perturbative field theory. The example was started by therelation $\Psi(\Phi)=Z…
We propose the investigation of asymptotically anti de-Sitter space-times with cylindrical symmetry under the AdS/CFT correspondence. These are solutions of Einstein's equations of General Relativity well known for a long time, and properties of the space-times itself are well known. However, the analysis of associated transport coefficients and dual theories has not been scrutinized in t…
In this project, we will study the worldsheet action of string theory on parallel plane, or ``pp'' waves, obtained in a certain limit of gravitational spaces used for the AdS/CFT correspondence, and show that by discretization, we obtain a quantum mechanical action that is obtained in the context of the Heisenberg spin chain for spins in a condensed matter system. We will also consider …

The AdS/CFT correspondence and its generalization, gauge/gravity duality, is a holographic duality relation equating a gravitational theory in a bulk background geometry with a field theory at the boundary of the geometry. Duality means that if the gravitational theory is weakly coupled, thus calculable, the field theory is nonperturbative. The first correspondence, for $AdS_5\times S^5$ …
The AdS/CFT correspondence relates holographically (meaning, a theory in a bulk geometry, with a theory on a boundary)a gravitational theory, usually of $AdS_{d+1}$ type, and sometimes coming from string theory, with a quantum field theory on the flat $d$-dimensional "boundary", one theory being weakly coupled, and the other strongly coupled. Initially, one used the gravitational side to …
String theory is a theory of quantum gravity, but also a unified theory of all interactions. It is a theory that usually requires a lot of background information. But there one can understand the basics by simplifying the quantum field theory and general relativity background to almost nothing. Within string theory, a duality called AdS/CFT correspondence was proposed between string theor…

The AdS/CFT correspondence relates a gravitational theory in AdS_{d+1} to a conformal field theory on its flat d-dimensional boundary, and a quasi-phenomenological approach was used to apply it to condensed matter systems. One application involves the holographic superconductivity. In order to describe a superconductor one needs a notion of temperature and a condensate. On the gravity sid…
The supersymmetric gauge theory N=4 Super-Yang-Mills in four dimensions is a superconformal theory and is believed to be integrable forany value of the coupling constant. In addition, due to the AdS/CFT conjecture, this theory is considered to be dual to the theory of superstrings in AdS_5 x S^5.Using integrability techniques, the computation of the spectrum of the theory is considered to…
In this project we propose three main topics for investigation. The first one named "Soft theorems" intends to expand our previous work on soft theorems, namely, to perform the same analysis done for graviton scattering but this time to gluon scattering. In the second part within this first project, we propose a novel extension of the newly discovered soft theorems by formulating them to …
