Montaña Faiget, Glòria (Fecha de defensa: 2022-07-08)
For many decades after the conception of the quark model in 1964, and the development of quantum chromodynamics (QCD) a few years later as the theory governing the strong interaction between quarks and ...
Bravo Prieto, Carlos (Fecha de defensa: 2022-06-20)
Quantum algorithms showing promising speedups with respect to their classical counterparts already exist. However, noise limits the quantum circuit depth, making the practical implementation of many ...

Star formation is a fundamental and still largely unsolved problem of astrophysics and cosmology. Its complexity stems from the complex interaction of turbulence, magnetic fields and gravity, and from ...
Mujal Torreblanca, Pere (Fecha de defensa: 2019-11-22)
In this thesis, we study the physical properties of several ultracold few-boson systems depending on the interactions between their constituents. Nowadays, experimentally, it is possible to have great ...
Katanaeva, Alisa (Fecha de defensa: 2021-02-10)
AdS/CFT correspondence combines ideas of holography and duality in a way that allows one to make calculations in the otherwise hardly accessible (strongly coupled) regime of the target theory. In this ...
Escrivá Mañas, Alberto (Fecha de defensa: 2021-06-21)
This thesis has been devoted to the study of the gravitational collapse of spherically symmetric perturbations on a Friedman-Robertson-Walker (FRW) universe filled by a perfect fluid. Large cosmological ...
Juárez Rodríguez, Carmen (Fecha de defensa: 2017-06-26)
Turbulence, magnetic fields and gravity driven flows are important for the formation of new stars. Although magnetic fields have been proven to be important in the formation of stars, only a few works ...
Gabbanelli, Luciano (Fecha de defensa: 2019-11-04)
For ninety years we have known that our universe is in expansion. Cosmological data favor an unknown form of intrinsic and fundamental uniform energy contributing approximately 68% of the total energy ...
Tous Mayol, José Luis (Fecha de defensa: 2024-04-12)
[eng] Astronomers have known of the existence of lenticular galaxies (S0) almost as long as they have known that there are other galaxies besides the Milky Way. While it is accepted that spiral galaxies ...
Cruces Mateo, Diego (Fecha de defensa: 2023-12-13)
[eng] From the observation of the cosmic microwave background radiation (CMBR) we know that the universe is isotropic on scales larger than ∼ 75 Megaparsec to at least one part in 100000. The leading ...
