The quick color switch allows an immediate change of the emitted color. The discovery has implications for diverse technologies in which fast color adjustment is required, such as display screens, quantum communication and miniaturized light sources
Quantum effects in X-rays make it possible to improve the resolution of the scan and protect the health of subjects and doctors
Meet Dr. Ohad Klein, PhD graduate in the Department of Mathematics at the Faculty of Exact Sciences, postdoctoral student at the Hebrew University and working at a startup company as an algorithmist
The French biotech start-up company called 'Carbios' succeeded in developing an enzymatic process to recycle the plastic polyethylene terephthalate (Polyethylene terephthalate) back to its component monomers, from which the finished polymer can be produced again
The shrimp has a particularly bright white color on its back and limbs that are intended to attract fish, which it 'cleanses' of pests it feeds on. An in-depth examination of the white substance using special electron microscopes revealed that the substance consists of an incredibly thin layer of very dense nanospheres (spheres of very tiny diameter)
Prof. Adi Aryeh: "We are standing at the threshold of a new technological world, and with it comes a host of new opportunities alongside a host of problems we have not yet encountered."
Doctoral student Benia Gros from the Department of Physics, the President's Scholar, has so far published 15 articles and one book, and presented his works dealing with dependent physical networks, at 9 conferences
Prof. Yael Shadami from the Faculty of Physics at the Technion focuses on the study of elementary particles including electrons, quarks, photons and gluons, and the interactions, or forces, that act between them. It tries to discover more elementary particles and interactions, beyond those described in the "standard model" of particle physics
Researchers have built surfaces from layers of atoms that slide over each other, thus causing the electrons inside to skip. In the future, they hope that it will be possible to develop advanced information technologies based on them
On May 10, three lectures in the field of quantum will be delivered to the general public, zoomed and free of charge. The event is being held in honor of World Quantum Day under the auspices of the Center for Quantum Information at the Hebrew University. No need to register in advance.
In an article published in the magazine Nature Physics, a team of researchers from Britain, the USA, Germany and Australia demonstrated for the first time the two cracks experiment in the timeline. Instead of spatial dispersion on a screen, the temporal crack created a dispersion in the light spectrum, and from the combination of another crack an interference pattern similar to the spatial pattern from the classic experiment was created. The experiment opens a window for the construction of time-varying optical instruments in a reliable and stable manner.
It started with very strange experimental results, continued in a new physical theory about the behavior of photons, and in the future may improve our smartphone screens and allow faster data communication. faster data
Measuring the light reflected from the algae makes it possible to calculate the light used for photosynthesis
In recent years, physicists from around the world have been discussing the construction of a muon accelerator instead of other conventional accelerators based on protons or electrons. Such an accelerator has clear advantages in discovering new physics, but its construction is accompanied by many technological challenges. In this article I will review the words of Prof. Nima Arkani-Hamed from the Institute for Advanced Studies in Princeton on the need to build such an accelerator.
The upgrade is expected to last several years and will include the construction of a new building to house the upgraded accelerator. Permilab is also planning to build a new particle detector, which will be used to study the particles produced by the Tevatron.
Researchers from the University of Santiago in Chile, working in the field of machine learning, have succeeded in developing an innovative method for identifying organic compounds based on the refractive index at a single optical wavelength
Has a room temperature conductor finally been discovered? very doubtful The scientific community suspects the reliability of the findings and the reason for this is clear, the researcher who signed the disclosure claimed this in the past and was repelled by his colleagues claiming errors in the experiment.
For the first time ever, researchers report the solid structure of pyridine-based chloronium ions. These compounds are known in the literature as intermediates in the oxidation reaction of secondary salts, but until now it has been very difficult to isolate them
Scientists are trying to answer one of the biggest open questions in physics
The winners are: Chuan Ha, University of Chicago, USA, Jeffrey Kelly, Scripps Research Institute, USA, Hiroaki Shuga, University of Tokyo, Japan
Led by doctoral student Mamon Safdi and Professor Yaron Bromberg from the Hebrew University, an experiment was carried out that demonstrates for the first time a substantial advantage in characterizing materials using entangled photons over classical light. The experiment published in the prestigious journal Nature Physics measured the light from entangled photons that were backscattered from a non-static scatterer. The results of the experiment showed that entangled photons reduce the measurement error by four times than non-entangled light, thus breaking the Kramer-Rao barrier for classical light.
The observatory, one of the most advanced in the world, will be used for tracking, sensing, hyperspectral photography and optical and quantum communication with satellites in orbit around the Earth
The discovery may be used as a breakthrough tool in the worlds of solar energy production, information processing and the like
The scientists of the institute and their research partners showed that the chance of an electron to pass through a tunnel at the junction between a molecule and a light field, and the manner in which it will do so, depend to a large extent on the chirality of both the molecule and the light
Researchers developed an algorithm that showed a basic quantum phenomenon: the immediate effect of one variable on other variables
