The present thesis studies a variety of cold atomic systems in artificial gauge fields. In the first part we focus on fractional quantum Hall effects, asking whether interesting topological states can be realized with cold ...
This thesis contains theoretical research on ultracold quantum gases in spatially periodic potentials, featuring high-frequency periodic driving, long-range interactions, or both. The largest part features deep potentials ...
The object of study of this thesis are dipolar systems in the quantum degenerate regime. In general, dealing with many-body systems and evaluating their properties requires to deal with the the Schrödinger equation. In the ...
Esta tesis es un trabajo teórico, en el que estudiamos la física de los átomos dipolares bosónicos ultrafríos en retículos ópticos. Éstos gases consisten de átomos o moléculas bosónicas, enfriados bajo la temperatura de ...
Understanding most of the physical and chemical phenomena determining the world around us requires the possibility to interrogate their main characters on their natural scale in space and time. The insulating or conductive ...
In this thesis, we have demonstrated various ultrafast optical parametric oscillators (OPOs) based on different nonlinear media. The thesis consists of OPO systems, novel techniques, designs, and concepts that has facilitated ...
Understanding and improving how light is converted into electricity in materials is one of the central goals in the field of optoelectronics. This basic physical process lies at the heart of several major technologies, ...
Control is important for transferring theoretical scientific knowledge into practical technology for applications in numerous fields. This is why coherent control study is significant on every timescale to have a complete ...
In this thesis, we address specific efforts towards developing the precise aspect of ultrashort laser pulse measurement in the context of biomedical research. The motivation for pursuing these new developments was triggered ...
(English) Ultrasonic moulding is a promising technology that could be used as a substitute for conventional injection moulding techniques. This relatively new technology has a lower energy consumption, and it could be a ...
Current market trend is moving to miniaturized specimens, especially in the biomedical field seeking high effective and less invasive treatrnent. Ultrasound (US) micromolding is a new technique developed to the aim of ...
Crystallization of honey is a common process of the honey industry. Liquid honey is preferred by most of the consumers and by food companies for ease of handling. Honey is commonly heated during pasteurization in order to ...
The morphological study of the Odontocete organ of Corti including possible pathological features resulting from sound over-exposure, represent a key conservation issue to assess the effects of acoustic pollution on marine ...
Transparent electrodes (TEs) are the essential elements of many optoelectronic devices such as solar cells, touch screens, organic LEDs, and LCDs. Consequently demand for TEs is growing very steeply and the market value ...
Não foi a arquitectura que, pelo seu contributo teórico e/ou inovador, entrou para a história das vanguardas da arquitectura aquela que mais nos interessou abordar, mas sim a proposta de um olhar atento sobre a arquitectura ...
The main goal of this thesis is to test the brittle-ductile (BD) interaction hypothesis of the lithosphere. The model uses the correlation of two parameters, the seismicity characterizing the brittle part and the attenuation ...
The importance of Geographical Indications (GI) has grown considerably in recent years as an opportunity for product differentiation for specific segments of the population. The continuous increase in the number of certified ...
This Ph.D. thesis mainly deals with temporal and deductive databases areas and the aim is to obtain a method for integrity constraint checking in bitemporal deductive databases, analyzing the temporal integrity constraint ...
La predicción precisa de los efectos producidos por el acoplamiento fluido estructura para cuerpos parcial o totalmente sumergidos, incluyendo superficies libres, es un problema de gran relevancia en la ingeniería naval ...
En esta tesis se desarrolla un sistema de tratamiento de informaciones geométricas con incertidumbre, basado en la propagación y fusión de regiones elipsoidales. Se adopta un modelo de incertidumbre acotada en el espacio ...
