Researchers from University of California, Santa Barbara, have developed a device that could prove the existence of non-Abelian anyons. These 2-dimensional quantum particles were theorized and mathematically predicted to exist but have not been synthesized till now.
A study published in the journal Nature has taken the first steps toward finding conclusive evidence of the existence of non-Abelian anyons. The researchers used graphene, an atomically thin material derived from graphite, to develop “an extremely low-defect, highly tunable device in which non-Abelian anyons should be much more accessible,” said a news release published on the university website.
These anyons are a type of quasiparticle that occur only in two-dimensional systems, with properties much less restricted than those of fermions and bosons. Here, when the system undergoes degeneration by exchanging two identical particles, there will be a change in state but the particles themselves will retain the same configuration.
