Integration and electrical manipulation of single-photon sources in 2-dimensional devices
Quantum nanophotonics aims at studying the interaction between matter and single photons at the nanoscale. Nanoscopic solid state light sources can be placed in near proximity to other photonic elements to engineer their ...
The application of broadband ultrafast spectroscopy to reveal structural, magnetic and electronic dynamics in quantum materials
In the last decades, quantum materials have received much attention in the field of condensed matter physics due, in part, to their exotic properties. These are difficult to understand as they result from multiple physical ...
Bound states in the continuum in planar anisotropic structures
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 ...
Dynamics of quantum mixtures
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 ...
Light harvesting and energy efficiency in perovskite solar cells and their applications
The environmental issues associated with the use of conventional fuels necessitates the utilisation of renewable energy sources, as well as the implementation of energy efficient designs, in order to decrease electricity ...
Large-scale imaging of optical antennas and single molecules
The interaction of light and matter is of crucial importance in fundamental science as well as in high-end technology. Ultimately, this concerns the interaction between a photon and a single quantum system, e.g. the ...
Quantum nonlinear optics at the single-photon level with cold Rydberg atoms
Photons are good candidates for carrying quantum information because they are very stable particles: they interact weakly with the medium and barely with each other. However, this has drawbacks when you want to process ...
New phenomena in high-quality suspended nanotube devices
Carbon nanotubes (CNTs) have attracted the attention of the scientific community since their discovery in the 90s. They are an excellent material for the development of research fields as diverse as nanomechanics or quantum ...
Deterministic control of nanoantenna and single-photon emitter interaction at the nanoscale
The study of light-matter interaction at the nanoscale is a very promising field of research, providing the possibility to manipulate the interaction with single quantum systems like single atoms, molecules, atomic defects ...
Machine learning for quantum physics and quantum physics for machine learning
Research at the intersection of machine learning (ML) and quantum physics is a recent growing field due to the enormous expectations and the success of both fields. ML is arguably one of the most promising technologies ...
Hybrid diffuse optical neuromonitoring of cerebral haemodynamics: from the smallest premature born infants to adults
Hybrid diffuse optical devices allows for the non-invasive and continuous monitoring of the cerebral haemodynamics and metabolism. Such devices can be portable and are relatively inexpensive, therefore available at the ...
Environmentally friendly nanocrystals synthesized and processed in ambient conditions for solution-processed solar cells
Due to the continuously increasing energy demand and the environmental concerns about climate changes raised by international community, alternative energy resources have been put under intense investigation for the past ...
Hybrid diffuse optics for translational oncology and nanobiophotonics: towards a theranostic approach for emerging cancer therapies
A pre-clinical mouse model of human clear cell renal cell carcinoma (ccRCC) was employed as a method to study the prognostic and theranostic potential of two, non-invasive, deep tissue, diffuse optical techniques, namely ...
Correlates of cerebral vasoreactivity measured by non-invasive diffuse optical measurements as biomarkers of brain injury risk
I have used and developed a practical new platform in the clinics for the noninvasive estimation of cerebral hemodynamics. The latform combines two diffuse optical techniques: near-infrared spectroscopy and diffuse ...
A cold-atom approach to topological quantum matter across the energy scale
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, ...
Development and study of novel mid-infrared frequency conversion sources
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 ...
Anomalous diffusion : from life to machines
Diffusion refers to numerous phenomena, by which particles and bodies of all kinds move throughout any kind of material, has emerged as one of the most prominent subjects in the study of complex systems. Motivated by the ...
Discerning between thermal and electronic effects in plasmonenhanced organic reactions
Since the pioneering work of Fujishima and Honda on titanium dioxide, TiO2, for the electrochemical photolysis of water under ultraviolet (UV) irradiation, semiconductor-based photocatalysis and photovoltaics have become ...
Novel planar photonic antennas to address the dynamic nanoarchitecture of biological membranes
The cell membrane is the encompassing protective shield of every cell and it is composed of a multitude of proteins, lipids and other molecules. The organization of the cell membrane is inextricably intertwined with its ...
Nanoscale control of near-field interactions between single emitters and photonic antennas-on-probe
Photonic antennas are metallic (or dielectric) nanoscale structures that convert propagating light into highly confined fields, and vice versa, in analogy to common radio antennas but on nanometric scales that lead to ...
