High-power, continuous-wave (cw), mid-infrared (mid-IR) laser sources are of interest for variety of applications such as trace gas detection and remote sensing, which require broad spectral coverage to address the most ...
(English) There is currently significant scientific and technological interest in ultrathin materials, with at least one dimension in the nm range or even smaller, since they possess features not achievable with their ...
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 ...
Noninvasive measurement of hemodynamics at the microvascular level may have a great impact on oncology in clinics for diagnosis, therapy planning and monitoring, and, in preclinical studies. To this end, diffuse optics is ...
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 ...
The field of photonics comprehends the generation, manipulation and detection of light (photons). Over the past decades, it has underpinned many of the technological advances upon which we rely on a daily basis, from our ...
Early detection of microorganisms in environmental and biomedical applications is critical for the effective response to potential pathogenic treats. Most traditional methods and instrumentation for the analysis of these ...
Quantum information science is a rapidly evolving field both from the theoretical and the experimental viewpoint, motivated by the fact that protocols exploiting quantum resources can perform tasks that are unfeasible in ...
In the recent decades, there has been a surge of interest in the wide array of emergent phenomena found in strongly correlated materials. Understanding the inner workings of this type of systems is a major challenge due ...
The migration of leukocytes from the blood stream to sites of injury and infection in the extravascular tissues is fundamental for the immune response. Two of the main receptors mediating this process are the integrins ...
The 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 ...
An important issue in today's information society is the security of data transmission against potential intruders, which always put at risk the confidentiality. Current methods to increase security require that the two ...
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 ...
In this manuscript we present an experimental and theoretical investigation of quantum-noise-limited measurement by nonlinear interferometry, or from another perspective, quantum-noise-limited interaction-based measurement. ...
Quantum mechanics was developed as a response to the inadequacy of classical physics in explaining certain physical phenomena. While it has proved immensely successful, it also presents several features that severely ...
(English) We perform quantum simulation on classical and quantum computers and set up a machine learning framework in which we can map out phase diagrams of known and unknown quantum many-body systems in an unsupervised ...
For a long time, quantum states of matter have been successfully characterized by the Ginzburg-Landau formalism that was able to classify all different types of phase transitions. This view changed with the discovery of ...
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 ...
Since discovering wave-particle duality, science has changed our perception of light and matter, especially at the subatomic level. Thanks to such discoveries, we have been able to develop and expand our scientific knowledge ...
As health systems fight against epidemics and infectious diseases, new forms of diagnostics need to be developed in order to meet the growing demand for services, often in locations without the necessary infrastructure. ...
