‘Quasiparticle’ collider could help devise better materials for solar cells, electronics

Physicists of all stripes seem to have one thing in common: They love smashing things together. This time-honored tradition has now been expanded from familiar particles like electrons, protons, and atomic nuclei to quasiparticles, which act like particles, but aren’t.
Quasiparticles are formed from groups of particles in a solid material that collectively behave like a unified particle (SN: 10/18/14, p. 22). The first quasiparticle collider, described May 11 in Nature, allows scientists to probe the faux-particles’ behavior. It’s a tool that could potentially lead researchers to improved materials for solar cells and electronics applications.
