Throughout the world, institutes for theoretical physics are an important tool for developing high-quality fundamental research. The International Centre for Theoretical Physics (ICTP), in collaboration with the State University of Sao Paulo (UNESP), created in 2011 the ICTP South American Institute for Fundamental Research located in the IFT-UNESP building in the city of Sao Paulo. The n…
We will investigate how ideas coming from the energy landscape for protein folding can now be used to understand genome folding and function.These applications of theoretical physics in biology will contribute to fortify this new interdisciplinary at ICTP-SAIFR. aplicações de física teórica na biologia vão contribuir para a ampliação desta área interedisciplinar no ICTP-SAIFR.

Recently, various ideas have resulted in enormous advances in the understanding of strongly coupled field theories and in particular of conformal field theories. From string theory, the AdS/CFT correspondence has allowed field theory computation previously impossible to perform including exact large-N results for 4 dimensional N=4 super Yang-Mills theory. From field theory, the conformal …

Cosmological surveys have proven helpful when describing the properties of the universe. They have been able to constrain the nature of its constituents and test its evolution with high precision. A pending task for future surveys is to shed light on the universe's initial conditions. The project aims to use data from photometric surveys, such as the Dark Energy Survey (DES) and the futur…
Upcoming galaxy and CMB surveys, including LSST and CMB-S4, are an unprecedented opportunity to explore the dark sector of the Universe. By mapping the distribution and shape of billions of galaxies, and by reconstructing the CMB gravitational lensing induced by large scale structures, these experiments offer complementary observables that shed light on the matter distribution and the gro…
Order-parameter fluctuations of Fermi liquids are a rich research field from the theoretical andexperimental point of view. Although the seminal zero sound excitation, a sound mode propagating in a three-dimensional fermion liquid, was computed by Landau and measured in experiments with He3 at low temperatures in the 50 and 60's, this field regained relevance with the increasing interest …

One important step for understanding the dualities relating the superstring in d + 1-dimensional Anti-de Sitter spacetimes and d-dimensional conformal field theories is theconstruction of calculable worldsheet theories in backgrounds with the presence of RamondRamond fields. In the particular case of pure NS-NS flux, a detailed understanding of theduality relating the tensionless limit of…
Supersymmetric localization was used to perform an exact computation of the expectation value of circular supersymmetric Wilson loops in N = 4 d = 4 Super Yang Mills. This expectation value was conjectured to be related to the superstring partition function on AdS_5xSÆ5. The pure spinor formalism gives a quantizable action on AdS_5xSÆ5 and the project proposal is to use supersymmetric loc…
A new kind of string theory, known as Ambitwistor String, was formulated by Mason and Skinner as a way to derive the CHY formalism. Using an approach more related to standard String Theory, the Chiral String model proposed by Warren Siegel gives an alternative view to the Ambitwistor model, and possible alpha prime corrections. Loop calculations might be si…
Over past years a new approach to compute S-matrix elements for N=4 D=4 Super Yang-Mills theory (SYM) has been developed. This framework makes use of the so-called spinor helicity formalism to write in a compact and elegant way several formulae for N=4 D=4 SYM scattering amplitudes. Color-kinematics duality, BCFW recursion relations, Kleiss-Kuijf relations among others are properties that…
