			Abstract
Sep 17 2025 - 10:00 to 11:45	Alejandro Pérez Rodríguez	Aspects of inflation beyond the single-field, slow-roll regime	In this thesis, we explore two departures from the single field, slow-roll paradigm of inflation. The first part is dedicated to warm inflation.
Sep 16 2025 - 12:00 to 13:45	Jesús Huertas Castellanos	Dynamical Cobordism in String Theory and Holography	This thesis investigates the intricate relationship between topology, gravity, and quantum field theory within String Theory, centering on the Cobordism Conjecture, which asserts that any consisten
Sep 16 2025 - 10:00 to 11:45	Roberta Angius	Aspects of symmetries throughout the String Theory Moduli Space	This thesis aims to explore various corners of the string theory moduli spaces using symmetries as a guiding principle to uncover properties of the corresponding theories a
Sep 15 2025 - 12:00 to 13:45	Ignacio Ruiz García	On the Asymptotic Global Structure of Duality Frames in Quantum Gravity	This thesis studies the global asymptotic structure of moduli spaces in effective field theories compatible with Quantum Gravity, focusing on the Swampland Distance Conj
Sep 15 2025 - 10:00 to 11:45	Luca Melotti	Exploring infinite distance limits of type II Calabi–Yau compactifications	This thesis explores infinite distance limits in the vector multiplet moduli space of type II string theory on Calabi–Yau threefolds.
Jul 24 2025 - 11:00 to 13:00	Nelson Hernández Rodríguez	Rotating Black Holes: NUT charges and effective Kerr Variants	This doctoral thesis focuses on the exploration of Kerr black holes and their thermodynamic properties, with the aim of broadening our understanding of these fascinating entities from the perspecti
Jan 10 2025 - 12:00 to 14:00	Alejandro Sopena González	Design and Implementation of Quantum Algorithms in the Noisy Intermediate Scale Quantum Era	Quantum computing is an emerging paradigm that leverages the principles of quantum mechanics to perform calculations potentially more efficiently than classical computing.
Dec 4 2024 - 10:00 to 14:00	Julia Vázquez	Measurement of the B(W->cq)/B(W->qq') decay branching fraction ratio with the CMS detector at the LHC and Uncertainty estimation of machine learning models in particle physics	Particle physics aims to understand the fundamental structure of matter and its interactions, relying on precise experimental measurements for its progress.
Oct 4 2024 - 11:00 to 12:00	Jonathan Machado	Journey through the ALPs	This thesis investigates the phenomenology of axion-like particles (ALPs), hypothetical pseudo-Goldstone bosons (pGB) which are the telltale of hidden spontaneously broken global symmetries.
Sep 23 2024 - 11:00 to 13:00	Arturo de Giorgi	The Phenomenological Landscape of Leptophilic ALPs	In this thesis, we consider model-building and phenomenology related to the simultaneous presence, alongside the Standard Model, of an Axion-Like Particle (ALP) and Heavy Neutral Leptons (HNLs).
