Design and Implementation of Quantum Algorithms in the Noisy Intermediate Scale Quantum Era

IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain

PhD Dissertation

Abstract: Quantum computing is an emerging paradigm that leverages the principles of quantum mechanics to perform calculations potentially more efficiently than classical computing. It is currently at a crucial stage of its development. Despite its rapid advancement and adoption in both academia and industry, there are still significant theoretical and practical challenges that must be […]

Exploring infinite distance limits of type II Calabi–Yau compactifications

Blue Room Instituto de Física Teórica (IFT) - C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain

PhD Dissertation

Speaker: Luca Melotti Institution: IFT UAM/CSIC Location&Place: Blue Room Abstract: This thesis explores infinite distance limits in the vector multiplet moduli space of type II string theory on Calabi–Yau threefolds. First we classify such limits, identify the towers of light states, and test the Emergence Proposal, which links IR kinetic terms to loop corrections from […]

On the Asymptotic Global Structure of Duality Frames in Quantum Gravity

Blue Room Instituto de Física Teórica (IFT) - C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain

PhD Dissertation

Speaker: Ignacio Ruiz García Institution: IFT UAM/CSIC Location&Place: Blue Room Abstract: This thesis studies the global asymptotic structure of moduli spaces in effective field theories compatible with Quantum Gravity, focusing on the Swampland Distance Conjecture. We develop taxonomy rules that determine the arrangement of towers of light states and duality frames at infinite distance, showing a […]

Aspects of symmetries throughout the String Theory Moduli Space

IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain

PhD Dissertation

Speaker: Roberta Angius Institution: IFT UAM/CSIC Location&Place: Red Room Abstract: 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 and their implications for spacetime dynamics. Within the Swampland Program, the absence of global symmetries in consistent quantum gravity […]

Dynamical Cobordism in String Theory and Holography

IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain

PhD Dissertation

Speaker: Jesús Huertas Castellanos Institution: IFT UAM/CSIC Location&Place: Red Room Abstract: 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 consistent quantum gravity theory must allow spacetime boundaries. It begins by introducing Dynamical Cobordism through models that realize end-of-the-world […]

Aspects of inflation beyond the single-field, slow-roll regime

IFT Seminar Room/Red Room Instituto de Física Teórica (IFT) -C. Nicolás Cabrera, 13-15, Fuencarral-El Pardo, Madrid, Spain

PhD Dissertation

Speaker: Alejandro Pérez Rodríguez Location&Place: Red Room Abstract: In this thesis, we explore two departures from the single field, slow-roll paradigm of inflation. The first part is dedicated to warm inflation. We revisit the theory of linear perturbations in this framework, develop computational techniques for the calculation of the primordial power spectrum and apply them to […]
