Squeezed-ligh-enhanced magnetometry in a high density atomic vapor
(Universitat Politècnica de Catalunya, 2022-09-29)
Doctoral thesis
Open Access(English) This thesis describes experiments that employ squeezed light to improve the performance of a sensitive optically-pumped magnetometer (OPM). The squeezed light source employs parametric amplification of vacuum ... -
Contributions to nanophotonics: linear, nonlinear and quantum phenomena
(Universitat Politècnica de Catalunya, 2022-10-18)
Doctoral thesis
Open Access(English) Nanophotonics can be defined as the science and technology studying the control optical fields at the nanoscale and their interaction with matter. In order to spatially control such fields we would need structures ... -
Quantum many-body physics with ultracold atoms and molecules: exact dynamics and machine learning
(Universitat Politècnica de Catalunya, 2022-09-20)
Doctoral thesis / Doctoral thesis
Open Access / Open Access(English) Quantum many-body physics poses a substantial computational challenge resulting from the exponential growth of the wave function complexity and many non-trivial correlations encoded in it. Studying many-body ... -
Resource theories of quantum dynamics

Open Access(English) As one of our most successful theories, quantum theory has greatly strengthened our understanding of nature and significantly advanced technologies. Specifically, quantum effects provide advantages in a broad ... -
Synthetic quantum matter using atoms and light
(Universitat Politècnica de Catalunya, 2022-10-21)
Doctoral thesis
Open AccessAtomic and optical physics are two fields closely connected by a shared range of energy scales, and the interactions between them. Atoms represent the most fundamental components of matter, and interactions with electromagnetic ... -
Laser-induced electron interferences from atoms and molecules
(Universitat Politècnica de Catalunya, 2022-07-25)
Doctoral thesis
Open AccessSince discovering wave-particle duality, science has changed our perception of light and matter, especially at the subatomic level. Thanks to such discoveries, we have been able to develop and expand our scientific knowledge ... -
Development of novel multimodal light-sheet fluorescence microscopes for in-vivo imaging of vertebrate organisms
(Universitat Politècnica de Catalunya, 2022-06-14)
Doctoral thesis
Open AccessThe observation of biological processes in their native environments is of critical importance for life science. While substantial information can be derived from the examination of in-vitro biological samples, in-vivo ... -
Atomic imaging of complex molecular
(Universitat Politècnica de Catalunya, 2022-07-27)
Doctoral thesis
Open AccessOne of the significant challenges of modern science is to track and image chemical reactions as they occur. The molecular movies, the precise spatiotemporal tracking of changes in their molecular dynamics, will provide a ... -
Quantum optics at its best: from quantum interferometry to quantum metrology
(Universitat Politècnica de Catalunya, 2022-07-28)
Doctoral thesis
Open AccessQuantum optics experiments are currently the most advanced techniques to under- stand, verify and simulate quantum phenomena. However, to access all the perfor- mance available in quantum states of light, one needs to ...
