Electrons that Act like Photons Reveal a Quantum Secret
TOKYO - September 13, 2025 - Researchers at Ehime University have made a groundbreaking discovery in the field of quantum materials, where electrons exhibit behavior similar to photons. This phenomenon, known as Dirac electrons, has been observed in specific organic compounds synthesized through chemical synthesis.
According to Dr. Taro Yamada, lead researcher on the project, "We've found that these electrons can transform themselves between standard and Dirac electrons depending on temperature." This transformation is tied to a unique feature in their band structures called linear band dispersion, which is a universal magnetic behavior observed in these materials.
The discovery deepens our understanding of quantum systems and points toward revolutionary applications in next-generation information and communication technologies. "These materials have the potential to enable faster and more efficient data transfer," said Dr. Yamada. "We're excited about the possibilities this opens up for the development of new technologies."
Quantum materials contain relativistic particles called Dirac electrons, which govern unique physical properties. In some cases, these particles can be massless and move at the speed of light, similar to photons. However, in certain organic charge-transfer complexes, they exhibit a distinctive behavior that sets them apart from conventional electrons.
The researchers synthesized the compounds using chemical synthesis techniques and observed the Dirac electron behavior through various experiments. "Our findings have significant implications for our understanding of quantum systems and the development of new materials with unique properties," said Dr. Yamada.
This breakthrough has far-reaching consequences, not only in material science but also in fields such as electronics and computing. The development of next-generation information and communication technologies could be accelerated by the discovery of these materials.
The research team is now working to further explore the properties of these materials and their potential applications. "We're eager to see where this discovery takes us," said Dr. Yamada. "The possibilities are endless, and we're excited to be at the forefront of this new frontier in material science."
