Currently there is a broad consensus that the unification of the four fundamental interactions of nature requires going beyond Einstein’s theory of General Relativity (GR). Einstein’s theory has successfully described the gravitational phenomena that we know and has important astrophysical implications. Remarkably, it predicts the existence of Black Holes, regions in which the spacetime is distorted in such a way that even light cannot escape from it. GR also predicts gravitational waves, which are ripples in space-time that propagate at the speed of light, transmitting changes in its curvature. Although general relativity successfully describes most of the gravitational phenomena that have been observed so far, it turns out to be incompatible with the description of the microscopic world characterized by quantum mechanics and in the explanation of the general composition of the universe. An attractive way to try to solve this inconsistency is string theory, which in turn requires supersymmetry, a kind of symmetry that relates bosons to fermions and under which the laws of nature are expected to be invariant at least up to a certain energy scale. The low energy limit of string theory is known as supergravity, which is a supersymmetric extension of GR.
In the last decades, one of the most considered approaches to understand the relationship between gravity and quantum field theories has been the AdS/CFT conjecture, which was originally conceived in the context of ten-dimensional superstring theory. Such correspondence has been subsequently extended to more general cases, connecting different asymptotically anti de sitter geometries with a great diversity of quantum systems, in particular in condensed matter theories.
Our research activity is focused on the construction of different extended (super)gravity models which could describe our Universe, and the analysis of different physical aspects, such as its solutions and thermodynamics, its stability, asymptotic symmetries, non- relativistic limits, and in some cases applications of these analysis in the context of holography. Thus, our research group aims to join efforts to contribute to the construction of a hitherto unknown final theory of quantum gravity.
The THEP group conducts research on the theoretical frontiers of High Energy Physics. The theoretical research deals with the fundamental interactions of nature addressing questions about matter and energy.
