THz light reversibly switches structurally ordered ferroaxiality in non-volatile memory between clockwise/ counterclockwise rotational patterns

"states switchable by magnetic or electric fields vulnerable to external influences/ degrade over time... overcome using ferroaxial rubidium iron dimolybdate hosting vortices of electric dipoles positionable in opposite directions without creating net magnetization/ electric polarization, made easier to control using circularly polarized THz pulses for switching... adjusting circularly polarized light's helicity (twist) pulses selectively stabilizes clockwise or anti-clockwise rotational arrangement of the electric dipoles”
