Quantum Trick Transforms Material Magnetism Sans Lasers

Theoretical physicists have discovered a laser-free method to control the magnetism of α-RuCl3, a thin material, by utilizing the electromagnetic fluctuations within an optical cavity. This breakthrough approach allows for the alteration of a material's magnetic properties solely through quantum fluctuations, providing a promising avenue for advancements in material science without the heat-related issues associated with intense laser methods. The researchers hope that this technique will enable the exploration of new material phases and enhance our understanding of the interplay between light and matter.
