The diverse properties of materials are determined by the behavior of the electrons moving within them. Naoya Kanazawa, associate professor at #UTokyo_IIS, is seeking to control the behavior of electrons and unlock new material properties by engineering the “curvature” of the space that electrons inhabit. The key lies in “spin topology control” and “band topology control,” which leverage the mathematical concept of topology. The precise manipulation of electrons offers the prospect of energy-efficient information processing technologies and next-generation memory.
