"The observations will be made possible through the control we have developed over the wave nature of free electrons," explains Prof. Kaminer
The 2023 Nobel Prize in Physics was awarded to three researchers: Pierre Agostini, Ferenc Krausz and Anne L'Huillier for "the development of their methods that produce extremely short attosecond pulses of light For the study of the dynamics of electrons inside the material"
"This is the first measurement ever made of the free fall of antimatter (antihydrogen) atoms that directly shows that they really fall down," explained Prof. Eli Sharid from the Physics Department at Ben-Gurion University of the Negev, the member of the ALPHA collaboration group
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."
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.
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.
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.
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 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
A team of researchers from Harvard University, MIT and Calcutta in collaboration with Google successfully simulated a traversable wormhole with the help of a quantum computer. The experiment performed on Google's quantum processor demonstrated the passage of information in the interlaced system. According to the principle of holography, the physics demonstrated in the experiment is the same as that of particles passing through wormholes. Although it was conducted on only nine qubits, the experiment is of great importance because it illustrates for the first time the possibility of testing quantum gravity with the help of entangled systems.
Inspired by the winners of the 2022 Nobel Prize in Physics, we will discuss Bell's theorem without introducing formulas and inequalities. In this article we will illustrate how experiments with entangled particles contradict the assumption that there are hidden variables and that quantum mechanics is indeed reliable.
During the visit of the Minister of Innovation, Orit Farkash HaCohen to the USA, she meets with senior officials and businessmen in order to strengthen the technological cooperation between the countries - after the Jerusalem Declaration. And collaborations in the field of quantum between countries are not common, given the far-reaching strategic implications of this field
On Richard Feynman's alternative formalism for time-dependent quantum mechanics - and the classical approximations that make it convenient for implementation in physics and theoretical chemistry
A group of researchers from Nanjing University and the University of Science and Technology of China developed an experiment that tested a model for dark energy. The results of the experiment ruled out the model in question that predicted a fundamental fifth force in nature.
Researchers from the Technion and Tel Aviv University have developed an innovative method to engineer quantum entanglement in a crystal, using computational learning tools
