When excitons and a large number of free electrons are simultaneously present however, the description of the qualitatively new — or «emergent» — properties of the material requires the introduction of new type of quasiparticles called Fermi polarons. (sciencedaily.com)
The quest to find Majorana quasiparticles in thin quantum wires began in 2001, spurred by Alexei Kitaev, then a physicist then at Microsoft Research. (sciencedaily.com)
Then they fired microwaves at the gyroid, and saw that the photons — which are massless bosons — were behaving like the Weyl fermion quasiparticles in Hasan's material. (scientificamerican.com)
