"Schematic picture of activity-induced ferromagnetism in quantum active matter. Here, moving atoms with spins exhibit the ferromagnetic order (i.e., aligning in one direction) like a flock of birds depicted above. Credit: Takasan et al 2024" (ScitechDaily, Strange Bird-Like Behavior in Atoms: Researchers Unveil New Magnetic Properties in Quantum Systems) Moving atoms (or ions) act like birds in the new ferromagnetic phenomenon. The first moving atom pulls the electromagnetic waves behind it, and those waves pull atoms to follow the leader particle. When electromagnetic waves hit the leading atoms, they create electromagnetic waves with hills and ditches. That phenomenon looks like a bird flock or ship that moves on the sea. That leading particle follows wave movement behind it. And the distance of the waves is always the same. The electromagnetic ditches between those hills can pull other atoms into that wave movement. The forward-moving movement can be virtual. If energy s
