Study says ‘Devil of Pines’ detected for the first time

A research team from the University of Illinois Urbana-Champaign in the United States claims they have succeeded in detecting a ‘demon plasmon’ in a study published in the scientific journal Nature. Scientists have for the first time confirmed the existence of a phenomenon known as the Pines demon, an idea proposed by theoretical physicist David Pines in mid-1956.

This is an example observed in a metallic strontium ruthenate metal (Sr2RuO4), which is responsible for different phenomena such as superconductivity and transition conditions in different semi-metals. The pine demon is considered a type of plasmon, which is a wave unit between electrons..

plasmons They are semi-particles that arise during quantized oscillations in plasma, the fourth state of matter. Scientists believe that there should be as many as five states of matter. The study describes how the discovery happened by chance during a study on the metal strontium ruthenate.

What are semiparticles?

Physics explains that quasiparticles are observed in microscopic environments, for example where a solid material has particles interacting with each other, such as electrons.

“At first we had no idea what it was. ‘Demons’ isn’t in the mainstream. The possibility popped up early on and we basically laughed at it. But once we started ignoring things, we started to suspect we had really found it,” said Ali Husain, one of the Quantinuum authors and researchers. “demon,” he said in a statement about the discovery.

The discovery was made by accident during a study with the metal Sr2RuO4, known for its resemblance to high-temperature superconductors.. Because the team did not know whether strontium ruthenate provides special conditions for a Pine devil, it was necessary to make microscopic calculations and analyze all the properties of the material to confirm the observation.

David Pines discovered that electrons in a solid such as a metal can behave differently. For example, electrons can interact to form a quasiparticle that has no mass, no electric charge, and is nearly invisible to humans. Well, just like a demon, Pines claims we can’t see him, but he’s there.

“Demons have been predicted theoretically for a long time, but experimenters have never studied them. We weren’t actually even looking. But we saw and found that we were doing exactly the right thing. This shows the importance of just measuring things. Most major discoveries are not planned. Professor of physics at the University of Urbana-Champaign and study “You’ll look at a new place and see what’s out there,” said its leader, Peter Abbamonte.
