‘Alice’s Rings’ Observed During Physics Experiment, According to Research

According to a new study published in the scientific journal Nature Communications, a team of astronomers has succeeded in observing mysterious ‘rings’ in the structure of reality. Known as ‘Alice rings’, these rings were found to form in an extremely cold gas during a laboratory experiment.It allows scientists to delve deeper into this strange phenomenon.

Named after the book Alice in Wonderland, the effect originates from the topological monopole, a hypothetical elementary particle that acts like a magnet on a single pole. Scientists suggest that the existence of only one magnetic pole is something that can be seen on earth. Like Alice’s. The research explains that monopoles may be due to quantum mechanics, which is responsible for the appearance of different forces and particles, but this idea is still considered purely theoretical.

The study, led by a team of scientists from the USA and Finland, claims that ‘Alice’s rings’ have been observed for the first time in an experiment created in the laboratory. For this, They placed 250,000 rubidium atoms in an airless chamber and hit them with lasers, cooling them to near absolute zero.

“Here, we present experimental proof of an Alice ring resulting from disruption of the topological unipolar defect in a dilute Bose-Einstein 87Rb gas condensation. Our results, according to detailed first-principle simulations, provide an unprecedented opportunity to explore the unique properties of compound excitation combining the topological properties of a monopole and a vortex ring. offers,” explains the study.

After creating the monopoles in the lab, the researchers noticed that each one turned into an ‘Alice ring’ with a slightly odd feature: Depending on the location where the scientists observed the ring, the magnetic charge changed.

The method of creating the ‘Alice’s ring’ is considered unique and can serve as a research resource for research on other topics such as cosmology, high energy physics and even the “hairy ball theorem”. algebraic topology, which studies the mathematics behind the shape of spaces.

“There’s something odd about this Alice ring. Depending on whether you’re looking through a near monopole ring or from the side, its charge looks different. So the ring reverses the charge of the objects you’re looking at,” said one of the study’s authors, Mikko Möttönen of Aalto University in Finland. .
