Sep 10 2021 - De 13:00 hasta 14:30 Alessandro Mininno Discrete symmetries, dynamical tadpoles, and the swampland

The thesis has the purpose to describe the role that discrete symmetries and dynamical tapdoles have in the Swampland program.

Sep 10 2021 - De 11:30 hasta 13:00 Fernando Arias Phenomenological and Cosmological Aspects of Axions and Other Nambu-Goldstone Bosons

Though the Standard Model of Particle Physics is an impressive theory with countless phenomena correctly predicted, it still presents some open problems.

Sep 10 2021 - De 10:30 hasta 12:00 Max Wiesner Quantum Corrections and the Swampland

In this thesis, we investigate the role of quantum corrections for certain Swampland constraints.

Sep 1 2021 - De 11:00 hasta 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 - De 11:30 hasta 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.

Ene 25 2021 - De 15:00 hasta 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 - De 11:00 hasta 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 - De 12:00 hasta 13:00 Christian Copetti 't Hooft anomalies & low energy effective actions

We present some of the results obtained during my thesis.

Sep 11 2020 - De 11:00 hasta 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 - De 11:00 hasta 13:00 Javier Martín García Quantum Complexity & Holography

This thesis develops recent work on the so called Volume-Complexity and Action-Complexity conjectures.
