Membrane protein nanoclustering as a functional unit of immune cells : from nanoscopy to single molecule dynamics
State-of-the-art biophysical techniques featuring high temporal and spatial resolution have allowed for the first time the direct visualization of individual transmembrane proteins on the cell membrane. These techniques ...
Solid-state quantum memory for photonic qubits
Optical quantum memories (QMs) are one of the fundamental building blocks in quantum information science (QIS). They might find important use in quantum communication and computation applications. Rare-earth ions (REIs) ...
From quantum foundations to quantum information protocols and back
Physics has two main ambitions: to predict and to understand. Indeed, physics aims for the prediction of all natural phenomena. Prediction entails modeling the correlation between an action, the input, and what is subsequently ...
Characterizing entanglement and quantum correlations constrained by symmetry
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 ...
Photonic applications based on the use of structured light
Structured light beams, this is, beams whose phase changes from point to point in the transverse plane, provides with an alternative tool to search for new applications, or simply to expand the capabilities of current ...
Plasmonic hot-carrier optoelectronics
The detection of light is of central importance in both fundamental science and applied technology. Photodetectors, which aim at transducing optical stimulus into measurable electrical signals, are ubiquitous to modern ...
Ultrathin metal transparent electrodes for the optoelectronics industry
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 ...
Optimal signal recovery for pulsed balanced detection
To measure quantum features in a classical world constrains us to extend the classical technology to the limit, inventing and discovering new schemes to use the classical devices, while reducing and filtering the sources ...
Diffuse optical monitoring of cerebral hemodynamics in experimental and clinical neurology
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 ...
Quantum gauge theory simulation with ultracold atoms
The study of ultracold atoms constitutes one of the hottest areas of atomic, molecular, and optical physics and quantum optics. The experimental and theoretical achievements in the last three decades in the control and ...
New laser speckle methods for in vivo blood flow imaging and monitoring
Blood flow and its regulation, as well as hemodynamics in general, are important for the health of tissues and hence the measurement of these quantities has many applications in research and clinical environments. Various ...
Nonlinear pulse compression
In this thesis I investigate two methods for generating ultrashort laser pulses in spectral regions which are ordinarily difficult to achieve by the existing techniques. These pulses are specially attractive in the study ...
Dynamics of spinor fermions
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 ...
Plasmon-soliton waves in metal-nonlinear dielectric planar structures
In this PhD thesis, we study properties of stationary transverse magnetic polarized waves in structures built of a Kerr-type nonlinear dielectric layer, metal and linear dielectric layers. Although these waves, called here ...
Photonic entanglement : new sources and new applications
Non-classical correlations, usually referred as entanglement, are ones of the most studied and discussed features of Quantum Mechanics, since the initial introduction of the concept in the decade of 1930s. Even nowadays, ...
