Physicists smash particle imitators
‘Quasiparticle’ collider could help devise better materials for solar cells, electronics
PARTICLE IMPERSONATOR Scientists have made the first quasiparticle collider, which smashes together faux-particles that appear in solids. In this illustration, quasiparticles (red and blue lines) collide head-on in a solid material (grid of spheres) releasing a burst of light.
