El control dinámico y determinístico de la luz en una escala espacial por debajo de la longitud de onda es un requisito clave para ampliar los conceptos y las funcionalidades de la macro-óptica hasta la escala nanométrica. ...
Prakash, Vindhiya (Fecha de defensa: 2021-12-16)
This thesis describes experimental work to generate and characterise single photons and photon pairs, with frequency content suitable for controlled interaction with cold rubidium atoms. We describe a photon-pair source, ...
García Guirado, Jose María (Fecha de defensa: 2018-10-30)
The race for fast and small that drives nowadays society has also reached the field of biosensing. Looking for efficient and cost effective biosensors for applications including screening and treatment monitoring, biomolecular ...
Valdés Escobar, Claudia Patricia (Fecha de defensa: 2014-12-15)
Blood flow and its regulation, as well as hemodynamics in general, are important for the health of tissues and hence the measurement of these quantities has many applications in research and clinical environments. Various ...

Carbon nanotubes (CNTs) have attracted the attention of the scientific community since their discovery in the 90s. They are an excellent material for the development of research fields as diverse as nanomechanics or quantum ...
Manzoni, Marco Tommaso (Fecha de defensa: 2017-10-19)
Photons travelling through free space do not interact with each other. This characteristic makes them perfect candidates to carry quantum information over long distances. On the other hand, processing the information they ...
Martínez Sánchez, Ignacio A. (Fecha de defensa: 2014-04-25)
Almost two centuries after the first observations of Robert Brown, the study of systems ruled by noise has become a significant part of modern physics and other so diverse situations, such as the stock market, personal ...
Coop, Simon (Fecha de defensa: 2018-09-06)
This thesis reports on theory and results from two experiments related to nonlinear behaviour in ensembles of optically-trapped ultracold atoms. The first experiment, performed at ICFO in Barcelona, regards the prediction ...
Lowinski, Jan (Fecha de defensa: 2024-01-19)
(English) Photons have emerged as the main candidates for carrying quantum information due to their weak interaction with the environment. Unfortunately, their limited interaction with one another poses challenges for ...
Grün, Alexander (Fecha de defensa: 2014-11-07)
In this thesis I investigate two methods for generating ultrashort laser pulses in spectral regions which are ordinarily difficult to achieve by the existing techniques. These pulses are specially attractive in the study ...
Rodríguez Echarri, Álvaro (Fecha de defensa: 2022-12-12)
(English) The fundamental science and technological applications of light-matter interactions on nanometer length scales form the field of study known as nanophotonics. Explorations in nanophotonics expand our understanding ...
Curchod, Florian John (Fecha de defensa: 2018-10-11)
This thesis focusses on the essential features of Quantum Theory that are systems in an entangled state and Bell nonlocal correlations. Here, we take the angle of a resource theory and are interested in understanding better ...
Würflinger, Lars Erik (Fecha de defensa: 2013-09-18)
Despite the success of quantum mechanics in predicting the outcomes of experiments in many branches of physics, the foundations of the theory have remained subject of research and dispute. At the basis of this struggle ...
Padhye, Anuja Arun (Fecha de defensa: 2020-06-04)
The ability to manipulate frequency of light, through parametric frequency conversion sources based on X(2) nonlinear materials, offers an effective route to spectral regions unapproachable by conventional lasers. Most ...
O'Donnell, Callum Francis (Fecha de defensa: 2019-04-26)
High-repetition-rate femtosecond laser sources are essential laboratory tools for spectroscopy, microscopy, amongst other applications. With the relative length of one femtosecond to one second being similar to the length ...
Rodríguez Fajardo, Valeria (Fecha de defensa: 2018-02-22)
The potential impact of noble metal nanoparticles (NPs) in diverse fields, particularly medicine, is tremendous. However, before NPs can be routinely used in clinical practices, it is fundamental to comprehensively study ...
Wei, Junxiong (Fecha de defensa: 2018-12-18)
The goal of this thesis has been the development of a new class of advanced solid-state photonic sources for the mid-infrared (mid-IR) spectral regions, where there exists a severe shortage of practical coherent laser ...
Winkler, Pamina M. (Fecha de defensa: 2020-11-27)
The cell membrane is the encompassing protective shield of every cell and it is composed of a multitude of proteins, lipids and other molecules. The organization of the cell membrane is inextricably intertwined with its ...
Ye, Hanyu (Fecha de defensa: 2019-05-03)
The mid-infrared (mid-IR) spectral region coincides with fundamental rotational-vibrational transitions of a large number of molecules in the gas phase. The strong interaction between mid-IR light sources and these gaseous ...
