With big screens, video games, and our imagination, lightsaber flares and catches when it hits. In reality, like a laser light show, the rays pass through each other, creating a cobweb pattern. The collision or interference only occurs in fiction. It also occurs in places with huge magnetic and electric fields that occur in nature only near large objects such as neutron stars. Here, a strong magnetic or electric field indicates that the vacuum is not really a void. Instead, if the rays intersect here, they will scatter in the rainbow. A weaker version of this effect has been observed in modern particle accelerators, but it is completely absent in our daily lives and even in normal laboratory environments.


Yuli Lyanda-Geller, a professor of physics and astronomy at Purdue University’s Faculty of Science, applied in collaboration with Aydin Keser and Oleg Sushkov at the University of New South Wales, Australia. Quantum field theory A non-perturbation method used to describe high-energy particles and extend them to analyze the behavior of so-called Dirac materials, which have recently attracted attention. They used extensions to obtain high-energy results known and beyond the general frameworks of condensed matter physics and material physics.

They proposed various experimental configurations with applied electric and magnetic fields and analyzed the best materials to allow experimental study of this quantum electrodynamic effect in non-accelerator settings. They then discovered that their results better explained some of the magnetic phenomena observed and studied in previous experiments.

Keser, Lyanda-Geller, and Sushkov have discovered that it is possible to produce this effect in a new class of materials containing bismuth, a solid solution containing antimony and tantalum hydride. With this knowledge, the effect can be studied and could lead to highly sensitive sensors and supercapacitors for energy storage that can be switched on and off by a controlled magnetic field.

“Most importantly, one of the deepest quantum mysteries in the universe can be tested and studied in small laboratory experiments,” Lyanda-Geller said. “Using these materials, we can study the effects of the universe. We can study what happens in. Neutron star From our laboratory. “

Yuli Lyanda-Geller is an expert in mesoscopic physics and interfering phenomena, optical phenomena of nanostructures, and physics of quantum information, and this paper is available online. Physical review letter..
