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 ...
Mukherjee, Samyobrata (Date of defense: 2021-10-05)
Bound states in the continuum (BICs) are modes that remain radiationless though they exist in the part of the spectrum that corresponds to radiating waves. They are a general wave phenomenon and following initial theoretical ...
Mestres Junqué, Pau (Date of defense: 2017-09-07)
Optical trapping and manipulation have emerged as powerful tools to investigate single microscopic objects in a controlled environment. Using the momentum carried by light, forces can be exerted to confine and manipulate ...
Mazzinghi, Chiara (Date of defense: 2023-07-26)
(English) In this work we propose and demonstrate cavity-enhanced polarization rotation to detect magnetic effects in transparent media with greater sensitivity at equal optical disturbance to the atomic medium. We use the ...
Baccari, Flavio (Date of defense: 2019-05-17)
Quantum 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 ...
Sainz, Ana Belén (Date of defense: 2014-02-10)
In the past century, experimental discoveries have witnessed phenomena in Nature which challenge our everyday classical intuition. In order to explain these facts, quantum theory was developed, which so far has been able ...
Tura i Brugués, Jordi (Date of defense: 2015-07-20)
Entanglement and nonlocal correlations constitute two fundamental resources for quantum information processing, as they allow for novel tasks that are otherwise impossible in a classical scenario. However, their elusive ...
Rueda Delgado, Diana Paola (Date of defense: 2019-07-30)
Organometal halide perovskites for solar cells are hybrid semiconductors that recently have caught the attention of the scientific community due to its excellent performance and attractive optical properties. Since then, ...
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 ...
Accanto, Nicolò (Date of defense: 2016-06-16)
Nanophotonics aims to understand and control the interaction of light-matter at the nanometer scale. Boosted by the development of nanotechnology and nanofabrication, nanophotonics is a thriving research field, with ...
Martin Ciurana, Ferran (Date of defense: 2017-12-14)
Optical magnetometers use magnetically-sensitive atomic ensembles and optical read-out to detect the amplitude of magnetic fields. They have become the most sensitive instruments for measuring low-frequency magnetic fields ...
González Cuadra, Daniel (Date of defense: 2020-12-11)
The outstanding progress achieved in the last decades to isolate and manipulate individual quantum systems has revolutionized the way in which quantum many-body phenomena, appearing across Nature's different energy scales, ...
Kumar, Gaurav (Date of defense: 2024-03-11)
(English) Bolometer technology, crucial for uncooled thermal detection in thermography, industrial inspection, monitoring, and surveillance applications, relies on thermistors primarily made of VOx, a-Si, and Si/SiGe QWs ...
Braungardt, Sibylle (Date of defense: 2011-07-12)
Tagliabue, Susanna (Date of defense: 2022-04-29)
(English) In the intensive care, the multimodal monitoring of the patient is crucial. The systemic physiology is routinely and comprehensively monitored but the practical monitoring of the brain is lacking. Hybrid diffuse ...
Devi, Kavita (Date of defense: 2013-10-24)
High-power, continuous-wave (cw) optical parametric oscillators (OPOs), from the ultraviolet (UV) and visible to the near- and mid-infrared (IR) wavelength range, are of interest for a variety of applications such as ...
Roque Fernández, Pablo Manuel de (Date of defense: 2022-10-18)
(English) Nanophotonics can be defined as the science and technology studying the control optical fields at the nanoscale and their interaction with matter. In order to spatially control such fields we would need structures ...
Neumann, Lars (Date of defense: 2012-04-18)
Un tema central en la ciencia y la tecnología es la exploración y explotación de sistemas cada vez más pequeños por medio de técnicas ópticas. A menudo, la longitud de onda viene dictada por el sistema de interés: los ...
Julià Farré, Sergi (Date of defense: 2022-06-28)
The last decades have witnessed impressive technical advances in all the fields of quantum science, including solid-state systems or atomic, molecular, and optical physics, allowing one to control materials at the microscopic ...
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, ...
