A new quasiparticle, which forms in a semiconductor and is made up of electrons mixed with areas in which electrons are missing, has been unexpectedly discovered by physicists. Researchers are calling the part-particle, part-liquid quantum droplet a "dropleton." "It's a particle inside matter, and it is an entity whose properties are determined by its environment," said Philipps University Marburg's Mackillo Kira, one of the researchers who made the discovery. The physics community is excited by the dropleton's potential in helping them study the quantum mechanics of so-called many-body systems.
