About
I'm fascinated by the potential of altermagnets (as shown in the image below) which are highly spin-active yet display no overall magnetic fields. I explore these unique materials with a vision to develop computing solutions that are denser, faster, and more energy-efficient.
CrSb crystal. The quantum mechanical 'clouds' of electron densities (cyan and magenta for opposite spins) are related to each other by rotating and mirroring them. Photo credits: Libor Šmejkal and Anna Birk Hellenes.
