Researchers from the University of Tokyo and RIKEN have discovered that increasing particle motility and repulsive forces between atoms can induce and maintain an ordered state called ferromagnetism.
This finding extends the concept of active matter to quantum systems and has implications for technological advancements in magnetic memory and quantum computing.
The researchers created a theoretical model inspired by flocking birds to demonstrate the mechanism behind the ordered state in a quantum system.
The reliability of their finding was confirmed through computer simulations, mean-field theory, statistical theory, and mathematical proofs.
