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

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.

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.
