Schmidt, Peter, 1989- (Date of defense: 2019-04-16)
Transition metal dichalcogenides (TMDs) are semiconducting layered materials that can be isolated up to the limit of a single atomic layer. Next to graphene, they are some of the most intensively studied materials within ...
Raventós Ribera, David (Date of defense: 2019-04-15)
Understand and tame complex quantum mechanical systems to build quantum technologies is one of the most important scientific endeavour nowadays. In this effort, Atomic, molecular and Optical systems have clearly played a ...
Hernández Santana, Senaida (Date of defense: 2019-04-12)
Quantum Mechanics was established as the theory of the microscopic world, which allowed to understand processes in atoms and molecules. Its emergence led to a new scientific paradigm that quickly spread to different research ...
Bourdoncle, Boris (Date of defense: 2019-02-13)
The twentieth century was marked by two scientific revolutions. On the one hand, quantum mechanics questioned our understanding of nature and physics. On the other hand, came the realisation that information could be treated ...
Salavrakos, Alexia (Date of defense: 2019-03-26)
The technological era that we live in is sometimes described as the Information Age. Colossal amounts of data are generated every day and considerable effort is put into creating technologies to process, store and transmit ...
García Guirado, Jose María (Date of defense: 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 ...
Canals Casals, Josep (Date of defense: 2018-10-18)
High-power, high-repetition-rate coherent picosecond sources with high beam quality are of great interest for many scientific and technological applications. For example, coherent sources at the ultraviolet (UV) spectrum ...
Ricci, Francesco, 1987- (Date of defense: 2019-02-22)
Levitodynamics addresses the levitation and manipulation of micro- and nanoresonators with the purpose of studying their dynamics. This emerging field has attracted much attention over the last few years owing to unprecedented ...
Laparra Cuervo, Lara (Date of defense: 2018-03-28)
The arrival of super-resolution techniques has driven researchers to explore biological areas that were unreachable before. Such techniques not only allowed the improvement of spatial resolution in images but also the ...
Maffei, Maria (Date of defense: 2019-01-29)
Differently from the majority of the other phases of matter, which are characterized by local order parameters, the topological phases are characterized by integer or semi-integer numbers, the topological invariants, which ...
Hancu, Ion Michael (Date of defense: 2019-01-18)
The emission and detection of light is a main pillar of both fundamental research and the advancement of modern technologies. From digital communications and quantum computing to novel cancer treatments and faded jeans, ...
Meng, Lijun (Date of defense: 2018-12-11)
Surface plasmons, which are characteristic oscillations of induced charges at metal surfaces that can interact strongly with light, are a key topic in nanophotonics. It can tightly confine the optical electric energy in ...
Morell Bennasser, Nicolás (Date of defense: 2018-12-17)
Suspended monolayer transition metal dichalcogenides (TMD) aremembranes that combine ultralow mass and exceptional optical prop-erties, making them intriguing materials for opto-mechanical applica-tions. However, the low ...
Wei, Junxiong (Date of defense: 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 ...
Martínez Saavedra, José Ramón (Date of defense: 2018-12-10)
Nanophotonics is one of today’s basic sciences and technologies: an in-depth understanding of the interaction between light and matter on the nano-scale, besides its intrinsic associated scientific interest, enables the ...
Lindner, Claus (Date of defense: 2017-03-24)
Several clinical studies for non-invasive estimation of tissue hemodynamics by the combination of two diffuse optical techniques, time-resolved and diffuse correlation spectroscopy, were carried out in collaboration with ...
Schwender, Jill (Date of defense: 2018-11-12)
In recent years, carbon nanotube and graphene mechanical resonators have attracted considerable attention because of their unique properties. Their high resonance frequencies, high quality factors and their ultra-low mass ...
Terborg, Roland A. (Date of defense: 2018-10-19)
As health systems fight against epidemics and infectious diseases, new forms of diagnostics need to be developed in order to meet the growing demand for services, often in locations without the necessary infrastructure. ...
Gopalan, Kavitha Kalavoor (Date of defense: 2018-10-22)
The mid-infrared (mid-IR) spectral region, with wavelengths between 3 and 15 µm, is known for a wide range of applications ranging from spectroscopic sensing to thermal imaging. However, despite the strong technological ...
Lampo, Aniello (Date of defense: 2018-10-02)
Quantum Brownian motion represents a paradigmatic model of open quantum system, namely a system which cannot be treated as an isolated one, because of the unavoidable interaction with the surrounding environment. In this ...
