On July 1, Javier Moreno successfully defended his thesis entitled “Higher-curvature gravity and entanglement entropy”. His work was guided by Dra. Olivera Miskovic (PUCV – HolographyCL) and Dr. Rodrigo Olea (UNAB – HolographyCL), and his committee was formed by Dr. Dumitru Astefanesei (PUCV), Dr. Ignacio Araya (UNAP), and Dr. Pablo Bueno (CERN).
The results of the thesis include classification and characterization of a particular family of theories dubbed as Generalized quasi-topological gravities. These theories provide useful toy models in the context of the gauge/gravity duality, allowing to gain insight on universal properties of strongly correlated systems. A particularly interesting quantity that can be computed through the AdS/CFT correspondence is entanglement entropy. In this line, the thesis includes results on its dependence on the shape of the entangling region, for both CFTs dual to Einstein gravity and general ones.
The work developed during the PhD studies resulted in six articles published in Journal of High Energy Physics, Physical Review D and Classical and Quantum Gravity. In the latter journal, an additional manuscript is currently under revision.
