Schädler, Kevin Gerd (Data de defensa: 2018-05-22)
Photonics aims to manipulate light by controlling its interactions with matter to enable novel optical technologies for communication, information processing and sensing. Current efforts strive to enter the regime of quantum ...
Alves, Natália Domingues (Data de defensa: 2023-06-16)
(English) This thesis studies, using simulation and experiment, the motional dynamics of a single atom in an optical dipole trap. The optical dipole trap we study is a single-beam, red-detuned, far-off-resonance trap (FORT). ...
Gündoğan, Mustafa (Data de defensa: 2015-10-22)
Optical quantum memories (QMs) are one of the fundamental building blocks in quantum information science (QIS). They might find important use in quantum communication and computation applications. Rare-earth ions (REIs) ...
Borovkova, Olga (Data de defensa: 2013-10-11)
Optical solitons provide unique opportunities for the control of light‐bylight. Today, the field of soliton formation in natural materials is mature, as the main properties of the possible soliton states are well understood. ...
Taghipour, Nima (Data de defensa: 2023-03-21)
(English) Colloidal semiconductors quantum dots (CQDs) have emerged as a promising solutionprocessed gain material that can be engineered via low-cost and scalable chemical techniques. Owing to quantum confinement, their ...
Steinlechner, Fabian (Data de defensa: 2015-12-14)
The nonlocal correlations of entangled systems are a feature inherent to quantum theory that is fundamentally at odds with our common-sense notions of realism and locality. Additionally, entanglement is an essential resource ...
Keary, Sarah (Data de defensa: 2022-02-28)
The main goal of this thesis was to contribute to the understanding of the nanoscale lateral organisation of key proteins in adhesion complexes. For this, we exploited single molecule localisation-based super-resolution ...
Beian, Mussie (Data de defensa: 2016-06-22)
Spatially indirect excitons, being composite bosons, are attractive candidates to explore correlated many-body systems. They possess an inherent large electric dipole, a four-fold spin manifold, and can be studied via the ...
Remesh, Vikas (Data de defensa: 2020-06-08)
The study of light-driven physical processes generated in nanomaterials require shorter (in time, or broader in frequency) laser pulses with techniques to tailor its phase and temporal/spectral characteristics at the ...
Gellings, Esther (Data de defensa: 2020-02-21)
At room temperature, individual molecules can be found in different conformations due to intrinsic and extrinsic factors which are reflected in spectral variability. When detecting single molecules, the ensemble average ...
Gómez Kabelka, Pau (Data de defensa: 2021-09-28)
In this work we demonstrate the first realization of a comagnetormeter in the ultracold regime. In comparison to regular magnetometers, which are designed to maximize their magnetic field sensitivity, a comagnetometer uses ...
Zielińska, Joanna Ada (Data de defensa: 2018-03-19)
This thesis studies different designs of optical parametric oscillators as sources of atom-resonant quantum light resonant with the rubidium D1 line.We analyze the mode structure and filtering techniques in a conventional ...
Troullinou, Charikleia (Data de defensa: 2022-09-29)
(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 ...
Marro Sánchez, Mònica (Data de defensa: 2013-07-12)
Since its discovery in 1928, Raman spectroscopy (RS) has produced a revolution in the fields of analytical chemistry and molecular detection. Thanks to the latest technical advances, the expectations of the applicability ...
Aviles-Espinosa, Rodrigo (Data de defensa: 2013-03-27)
The requirement for imaging living structures with higher contrast and resolution has been covered by the inherent advantages offered by nonlinear microscopy (NLM). However, to achieve its full potential there are still ...
Suárez Rojas, Noslen (Data de defensa: 2018-01-23)
In this thesis, we develop a general theory to describe the dynamics of electrons that are ionized when an atom or molecule is exposed to a strong low frequency laser field. Our approach extends and improves the well-established ...
Alcaraz Iranzo, David (Data de defensa: 2020-06-23)
Graphene is the first of the 2D-material family. It is formed by carbon atoms arranged in a honeycomb lattice, which confers it intriguing physical properties that are still being discovered nowadays. A fundamental advantage ...
Negash, Awoke (Data de defensa: 2017-11-29)
The resolution of a conventional fluorescence microscope image is diffraction limited which achieves a spatial resolution of 200nm lateral and 500nm axial. Recently, many superresolution fluorescence microscopy techniques ...
Argüello-Luengo, Javier (Data de defensa: 2022-10-21)
Atomic 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 ...
Moreno Mencía, David (Data de defensa: 2021-11-22)
