Researchers have discovered a way to store information using a rare class of materials called ferroaxials, which rely on swirling electric dipoles instead of magnetism or charge. These vortex-like states are naturally stable and resistant to outside interference, but until now were almost impossible to control. By using circularly polarized terahertz light, scientists were able to flip these tiny rotational patterns on command, opening the door to a new form of robust, ultrafast, and long-lasting data storage.
