"Discovery of Photon-like Electrons in Four-Dimensional Material"

Scientists have discovered a method to selectively observe Dirac electrons in materials using electron spin resonance, allowing for the determination of their scope of action and energies in a four-dimensional world consisting of positions (x, y, z) and energy (E). This advancement in understanding Dirac electrons reveals that their velocity is anisotropic and depends on their direction and location, rather than being a constant velocity of light, potentially leading to unprecedented electronic properties in materials for efficient computation and communication.
