|---|---|---|---|---|
 | Sep 1 2021 - 11:00 to 12:30 | Rubén Arjona | Exploring the nature of dark energy with modified gravity and machine learning | This dissertation is focused in exploring the nature of the origin of the accelerated expansion of the Universe at late times from the theoretical point of view through modifications of the theory |
| | Jul 16 2021 - 11:30 to 13:00 | Raquel Santos | The quest for Quantum Gravity: from Weyl invariance to transverse theories | The first part of the thesis is devoted to the study of quadratic (in curvature) theories of gravity when treated in the First Order formalism. |
| | Jan 25 2021 - 15:00 to 17:00 | Manuel Trashorras | Primordial Black Hole cluster dynamics and early Universe models | In this thesis we have studied a particular inflationary model of the early-Universe dynamics, the Higgs-Dilaton Model, a viable extension of the Standard Model |
| | Sep 23 2020 - 11:00 to 12:00 | Alejandro Ruipérez | Black holes in string theory with higher-derivative corrections | The low-energy limit of superstring theories admits a description in terms of an effective field theory for its massless modes. |
| | Sep 17 2020 - 12:00 to 13:00 | Christian Copetti | 't Hooft anomalies & low energy effective actions | We present some of the results obtained during my thesis. |
| | Sep 11 2020 - 11:00 to 13:15 | Alvaro Herraez | 4-Forms and Membranes: From the Flux Potential to the Swampland | This thesis explores different aspects of type II string compactifications. In the first part, we will focus on the structure of the perturbative flux-induced scalar potential. |
 | Sep 4 2020 - 11:00 to 13:00 | Javier Martín García | Quantum Complexity & Holography | This thesis develops recent work on the so called Volume-Complexity and Action-Complexity conjectures. |
| | Apr 17 2020 - 11:00 to 13:00 | Jose Angel Romero | Study of Mesonic Observables from a Mixed Action Lattice QCD Formalism | We propose a Lattice QCD mixed-action approach in which sea quarks are regularized using Nf = 2 + 1 non-perturbatively O(a)-improved Wilson fermions |
| | Dec 16 2019 - 11:30 to 13:30 | Eduardo Ibáñez Bribian | Volume (in)dependence in Yang-Mills theories | This thesis aims to study of the relationship between gauge and spacetime degrees of freedom in finite volume Yang-Mills theories with twisted boundary conditions. |
| | Dec 13 2019 - 12:30 to 14:00 | Raoul Letschka | Quantum Foundation of Infrared Physics | In this thesis we will take a look on the infrared (IR) and collinear limit of QED and pertur- bative gravity. |
