Permilab: We discovered clues to new physics

Last Tuesday, the Premilab laboratories in the United States announced that the muon's magnetic moment does not match the theoretical calculations. The experiment conducted in the state of Illinois confirms the anomaly that was discovered several years ago. Is this evidence?

"In these days," says Prof. Polman, "in which enormous efforts are being invested in all the countries of the world in order to develop quantum technologies, such as the quantum computer, it is extremely important to understand the basic processes that occur when quantum operations are performed on a particle that change its state.

In the study, the scientists examined collisions that occur between the molecules. Collisions of atoms have been studied in the past, but atoms - according to classical physics - are spherical, while molecules have an elongated structure. The structure of a colliding body affects the way it will move after the collision. Will elongated molecules behave differently from spherical atoms? And is knowing their shape enough to predict the outcome of the collision? Illustration: pixabay.com.

A particle moving along the energy band. Blue and red color mark particles with spin up and spin down. During the experiment, the particles move from the center to the edges of the energy band and acquire the geometric phase of Zak. Illustration: Technion barges

After 25 years: German and American researchers managed to measure a geometric phase in solids

This phase was discovered about 25 years ago by Prof. Yehoshua Zak of the Technion and is named after him - "Zak Phase"
