Scientists have finally found a “demon” subatomic particle that was predicted to exist nearly seven decades ago and speculated to play an important role in the behaviours of a range of metals and alloys, including superconductors. Physcist David Pines in 1956 theorised that electrons, which normally have a mass and negative electric charge, can under some conditions combine to form a composite “demon” particle that is massless, neutral and does not interact with light. These theorised interesting properties, however, made these particles elude detection – until now. After a nearly 70-year search for these subatomic entities, researchers, including those from the University of Illinois Urbana-Champaign, have finally found signatures of Dr Pines’ “demon” particles in the metal strontium ruthenate. “Demons have been theoretically conjectured for a long time, but experimentalists never studied them. In fact, we weren’t even looking for it. But it turned out we were doing exactly the right thing, and we found it,” study co-author Peter Abbamonte said. Electrons – which are distributed in different energy bands within atoms – are known to lose their individuality in solids with electric interactions making the particles combine to form collective units. With some threshold energy, studies have also shown electrons can form composite particles called plasmons with a new charge and mass. However, the mass is so large that these plasmon particles cannot form with the kind of energies available at room temperature. Revelations on room-temperature semiconductors are considered to be one of the “holy grails” of physics. But Dr Pines theorised that if a solid has electrons in more than one energy band, as many metals do, their respective plasmons may combine in an out-of-phase pattern to form a new plasmon that is massless and neutral – a demon. Since these special particles are massless, he argued they can form with any energy and may exist at all temperatures – leading to speculation that the demons have important effects on the behaviour of some metals with multiple energy bands. “The vast majority of experiments are done with light and measure optical properties, but being electrically neutral means that demons don’t interact with light,” Dr Abbamonte explained. So a completely new experiment was needed to detect them. In the research, scientists were studying the compound strontium ruthenate as it is similar to high-temperature superconductors – a special kind of material where electrical resistance vanishes. For a survey of the metal’s electronic properties, they synthesised high-quality samples of the metal. They then applied a technique to study the metal that uses energy from electrons shot into the metal to directly observe the metal’s features, including plasmons that form. During their observation of the electron interactions, scientists found something unusual – an electronic mode with no mass. “At first, we had no idea what it was. Demons are not in the mainstream. The possibility came up early on, and we basically laughed it off. But, as we started ruling things out, we started to suspect that we had really found the demon,” Ali Husain, another author of the study, said. Researchers then sought to calculate how electrons are distributed across bands inside strontium ruthenate. Predictions by Dr Pines indicate there are specific conditions when “demons” are likely to form, and it remained unknown whether strontium ruthenate would have the particle. “We had to perform a microscopic calculation to clarify what was going on. When we did this, we found a particle consisting of two electron bands oscillating out-of-phase with nearly equal magnitude, just like Pines described,” found Edwin Huang, another author of the study. “Our study confirms a 67-year-old prediction and indicates that demons may be a pervasive feature of multiband metals,” scientists wrote in the study.

Williams have confirmed that American rookie Logan Sargeant will remain with the team next season. The British outfit’s move to retain Sargeant, 22, for a second campaign completes the 20-driver grid for 2024. Sargeant, who scored just one point during a difficult first season, will race alongside Alex Albon after the London-born Thai’s seat had already been confirmed. “I am thrilled to be continuing with Williams Racing for the 2024 season,” said Sargeant. “It has been an incredible journey with the team so far and I am grateful for the opportunity to continue developing as a driver within such a talented and dedicated group. “We have exciting plans for the future and I can’t wait to contribute to the team’s success in the coming year.” Sargeant claimed his maiden point in Formula One – the first American to score in the sport since Michael Andretti 30 years ago for McLaren – after Lewis Hamilton and Charles Leclerc were both disqualified from the United States Grand Prix in Austin in October. Albon finished the year with an impressive 27 points to help Williams land seventh in the constructors’ championship, the team’s best result for six seasons. “I am pleased to continue our journey with Logan into 2024,” said team principal James Vowles. “Logan has demonstrated immense skill whilst under the pressure of the world stage, making him a perfect fit for our team. “We have great confidence in his abilities and believe that together we can achieve even greater success in the upcoming season.” The Formula One season will start in Bahrain on March 2.
