Nandy, Biplob Kumar (Data de defensa: 2020-12-02)
Tunable narrow-linewidth and broadband laser sources in the mid-infrared (mid-IR) wavelength range are extremely desirable in all time scales for their several useful applications in spectroscopy, imaging, optical communication ...
Sánchez Peacham, Daniel Alexander (Data de defensa: 2020-01-27)
The continuous development of laser sources delivering ultra-short light pulses underpins much of the current progress in experimental science, particularly in the domain of physics concerned with strong-field phenomena. ...
Olarte, Omar E. (Data de defensa: 2014-03-20)
In the quest for better and faster images of cellular and subcellular structures, biology-oriented optical microscopes have advanced significantly in the last few decades. Novel microscopy techniques such as non-linear ...
Bernardello, Matteo (Data de defensa: 2022-06-14)
The observation of biological processes in their native environments is of critical importance for life science. While substantial information can be derived from the examination of in-vitro biological samples, in-vivo ...
Supic, Ivan (Data de defensa: 2018-09-19)
The last two decades have been a very fruitful period for the fundamental research related to quantum information theory. Today we have a fairly good understanding of how intrinsically quantum properties affect various ...
Blanco Núñez, Igor D. (Data de defensa: 2015-01-31)
The study of the brain using diffuse optical methods has progressed rapidly in the recent years. The possibility of studying the cerebral microvasculature in addition to the portability and low cost of these devices, opens ...
Liu, Quan (Data de defensa: 2018-03-23)
Solution-processed thin film solar cells emerged as very promising photovoltaic technologies suitable for a low cost roll-to-roll upscale production. Such thin film character also ensures lightweight and flexibility for ...
Gieseler, Jan (Data de defensa: 2014-02-03)
Nanotechnology was named one of the key enabling technologies by the European Commission and its tremendous impact was envisioned early by 20th century physicist R.Feynman in his now oft-quoted talk "Plenty of Room at the ...
Guenther, Nils Eric (Data de defensa: 2021-09-08)
At sufficiently low temperatures, fluids of bosonic particles may undergo a phase transition, below which a Bose-Einstein condensate (BEC) forms. The BEC is one of the most fundamental concepts in many-body quantum physics ...
Ebling, Ulrich (Data de defensa: 2014-11-03)
Ultracold atomic gases have established themselves as quantum systems, which are clean and offer a high degree of control over crucial parameters. They are well isolated from their environment and thus offer the possibility ...
Sridhar, Susmita (Data de defensa: 2016-10-05)
Polarization gating imaging is a popular and widely used imaging technique in biomedical optics to sense tissues, deeper volumes, and also selectively probe sub-superficial volumes. Due to the "polarization memory" effect ...
Piga, Angelo (Data de defensa: 2020-03-30)
During the past two decades, thanks to the mutual fertilization of the research in quantum information and condensed matter, new approaches based on purely quantum features without any classical analog turned out to be ...
Beduini, Federica A. (Data de defensa: 2015-11-3)
This thesis analyses the effects of two-photon interference in a polarisation squeezed state under two different points of view: on one hand, it presents a new method to obtain the temporal wavefunction of a state of two ...
Vallés Marí, Adam (Data de defensa: 2017-02-14)
The work presented in this thesis, mostly experimental, is based on three main pillars: the concepts of entanglement, Bell's inequalities and coherence. Entanglement is a very special type of correlation that can exist ...
Raventós Ribera, David (Data de defensa: 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 ...
Alloing, Mathieu (Data de defensa: 2014-05-28)
In this thesis, we report experimental evidence of a "gray" condensate of excitons, as predicted theoretically by M. Combescot et al. Most importantly, the condensate is characterized by the macroscopic population of dark ...
Huwer, Jan Henning (Data de defensa: 2014-01-29)
One promising approach for future quantum networks is the combination of strings of trapped ions as quantum-information processors with entangled photon pairs produced by spontaneous parametric down conversion (SPDC) to ...
Woessner, Achim (Data de defensa: 2017-05-11)
Plasmons are charge oscillations coupled to electromagnetic radiation. One of their most intriguing properties is their deep subwavelength confinement resulting in strongly enhanced light-matter interaction. Metal plasmons ...
Schmidt, Peter, 1989- (Data de defensa: 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 ...
Heller, Lukas (Data de defensa: 2023-11-06)
(English) Quantum memories are devices that are able to store photonic quantum states and entanglement. Future quantum networks, which could enhance cybersecurity through quantum key distribution, improve the precision in ...
