    Vacuum Energy in Quantum Field Theory and Cosmology 

    Gómez Valent, Adrià (Date of defense: 2017-09-12)

    The cosmological constant appearing in Einstein’s equations is a key element of the ΛCDM standard cosmological model. This term performs, effectively, as pure vacuum energy, and is considered the easiest explanation of the ...

    Variational quantum architectures. Applications for noisy intermediate-scale quantum computers 

    Bravo Prieto, Carlos (Date of defense: 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 such quantum algorithms ...

    Wave propagation in metamaterials mimicking spacetime geometry: black holes and cosmic strings 

    Fernández Núñez, Isabel (Date of defense: 2018-07-19)

    In physics, it is common to find different phenomena being described by similar equations. A good analogy can make us look at a problem from a different point of view. In that way, ideas may be transferred from one field ...
