Certification of many-body systems
(Universitat Politècnica de Catalunya, 2019-05-17)
Tesis
Acceso abiertoQuantum physics is arguably both the most successful and the most counterintuitive physical theory of all times. Its extremely accurate predictions on the behaviour of microscopic particles have led to unprecedented ... -
Novel pulsed optical parametric sources in the mid-infrared and the application towards high-resolution molecular spectroscopy
(Universitat Politècnica de Catalunya, 2019-05-03)
Tesis
Acceso abiertoThe 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 ... -
The insulator-metal phase transition in VO2 measured at nanometer length scales and femtosecond time scales
(Universitat Politècnica de Catalunya, 2019-05-02)
Tesis
Acceso abiertoThe physics of transition-metal oxides presents a challenge to our current understanding of condensed matter physics. The main difficulty arises from a competition between electron-electron and electron-phonon interactions ... -
Novel femtosecond optical parametric oscillators in the infrared
(Universitat Politècnica de Catalunya, 2019-05-26)
Tesis
Acceso abiertoHigh-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 ... -
Exploring intersubbands in 2D materials
(Universitat Politècnica de Catalunya, 2019-04-16)
Tesis
Acceso abiertoTransition 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 ... -
Exact diagonalization studies of quantum simulators
(Universitat Politècnica de Catalunya, 2019-04-15)
Tesis
Acceso abiertoUnderstand 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 ... -
Local temperature and correlations in quantum many-body systems
(Universitat Politècnica de Catalunya, 2019-04-12)
Tesis
Acceso abiertoQuantum 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 ... -
Quantifying randomness from Bell nonlocality
(Universitat Politècnica de Catalunya, 2019-02-13)
Tesis
Acceso abiertoThe 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 ... -
New lab-on-a-chip strategies for enantio-selective and non-diffusion-limited biosensing
(Universitat Politècnica de Catalunya, 2018-10-30)
Tesis
Acceso abiertoThe 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 ... -
Picosecond, high-repetition-rate, optical parametric sources from the ultraviolet to the deep-infrared
(Universitat Politècnica de Catalunya, 2018-10-18)
Tesis
Acceso abiertoHigh-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 ... -
Levitodynamics toward force nano-sensors in vacuum
(Universitat Politècnica de Catalunya, 2019-02-22)
Tesis
Acceso abiertoLevitodynamics 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 ... -
Quantitative nanoscale imaging of synaptic protein organization
(Universitat Politècnica de Catalunya, 2018-03-28)
Tesis
Acceso abiertoThe 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 ...
