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.

Apple will start letting developers make apps for its upcoming ‘Vision Pro’ headset. The company has released its software development kit, or SDK, for VisionOS, the operating system that will run on the hardware. Apple announced its new headset at its Worldwide Developers Conference, earlier this month. It said then that the hardware would be available “early next year”, but that developers would be able to start creating experiences for it before then. Now it has released the first part of that work, in the form of that SDK. It gives developers the tools they need to start creating what Apple calls “spatial experiences” for the headset. Apple hopes developers will be able to “utilise the powerful and unique capabilities of Vision Pro and visionOS to design brand-new app experiences across a variety of categories including productivity, design, gaming, and more”. Next month, Apple will start holding labs in a range of cities – Cupertino, London, Munich, Shanghai, Singapore, and Tokyo – where developers will be able to submit their apps and actually test them on Vision Pro hardware. Apple engineers will also be on hand to ensure that the apps work on the new platform, Apple said. Development teams will also be able to apply for developer kits that will allow them to test their apps in their own facilities. Apple gave no information on what sort of form those kits would take – how similar they will be to the hardware that will eventually be released, for instance, and what restrictions they will have – or which and how many developers would get through that application process. Apple’s Vision Pro software is built on the foundational technology from other Apple platforms such as iOS and MacOS, and developers are able to use the same tools and frameworks to build apps for the new hardware. But as a “spatial computer”, the Vision Pro also requires entirely new ways of using apps, and so developers will likely need to test their apps on the platform to ensure they actually work as apps within the headset. “Apple Vision Pro redefines what’s possible on a computing platform. Developers can get started building visionOS apps using the powerful frameworks they already know, and take their development even further with new innovative tools and technologies like Reality Composer Pro, to design all-new experiences for their users,” said Susan Prescott, Apple’s vice president of worldwide developer relations. “By taking advantage of the space around the user, spatial computing unlocks new opportunities for our developers, and enables them to imagine new ways to help their users connect, be productive, and enjoy new types of entertainment. We can’t wait to see what our developer community dreams up.” Apple released the SDK, as well as new versions of its development tools, on its developer website. It is also publishing a range of tools aimed at developers, including new guidelines for how those Vision Pro apps should actually look and work.
