The efficient interaction of photons with single quantum emitters like nitrogen vacancy (NV) centres is essential for the elaboration of future integrated quantum optical devices. A promising strategy towards this goal ...
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 ...
One of the significant challenges of modern science is to track and image chemical reactions as they occur. The molecular movies, the precise spatiotemporal tracking of changes in their molecular dynamics, will provide a ...
The use of light, especially of laser light, is in many cases the most sensitive way to perform measurements. However, the highest sensitivity that can be achieved with laser light as probe is bounded by the standard quantum ...
(English) One of the fundamental goals of the physical chemistry community has always been to be able to follow the details of the evolution of chemical reactions in real-time. Besides the extreme temporal resolution ...
Attoscience aims to study electron dynamics in matter with unprecedented temporal resolution by using the shortest pulses generated on Earth. Currently, such resolution is only provided by sources that deliver attosecond ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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, ...
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 ...
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 ...
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 ...
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, ...
(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 ...
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 ...
