Whenever we find something new in this world, we have a tendency to want to know everything about it. In a world so full opportunity and discovery, it makes sense. With our immense ability to research and evaluate just about anything we find, why not find out everything that we can about, well, everything?
Sometimes though, we can find objects that totally shatter the conventional rules of what we thought we knew.
For example, a new crystalline material has been found that appears to have electronic properties never seen in the past. This unique new material was found recently and is made up of a mixture of aluminum and platinum.
It’s got a set of electronic properties that are unique, in that we have never seen their likes in the past. This was picked up in the Nature Physics science journal. Apparently, the structure is capable of producing Rarita-Schwinger fermions through its interior and also its Fermi arcs. That’s very interesting and shows a material state that behaves like an actual particle.
The finding is noted to be of significant importance moving forward. The research team working on it at the Paul Scherrer Institute, using the Swiss Synchrotron Light Source SLS, used this to observe the particles for the first time. It’s a very interesting finding and one that breaks away from a lot of conventional findings.
Indeed, there is a repeated pattern of atoms taking place in a cube-shaped style, forming a cell unit of up to two elements. Inside this particular crystalline formation, there is a different layout. Normally, there would be a symmetry of sorts taking place within. This is different, with a slightly offset design in the middle. This forms what is known as a helical line.
This is known as a chiral crystal – a pair of mirror images, in essence. It’s very exciting and is the kind of finding which is often exceptionally rare in these particular fields. By using the SLS X-ray in conjunction with photoelectron spectroscopy tools at PSI, they were able to look at these unique electrical properties.
They found that it was not only chiral; it was also topological, meaning that it shows resistance to defects.
The hope is that, in time, this kind of finding could be used to assist in the creation of high-end computing equipment, such as quantum computing, in the near future.
