Majorana anyone? Apr 15th 2012, 02:41 http://www.bbc.co.uk/news/science-environment-17695944 Quote: Scientists think they may finally have seen evidence for a famously elusive quarry in particle physics. The Majorana fermion was first predicted 75 years ago - a particle that could be its own anti-particle. Now Dutch researchers, who have devised some exotic and minute circuitry to test for the Majorana's existence, believe their results show the fermion to be real. The team has reported the details of its experiments in Science magazine... ..."If you take a solid material and you make the right combinations, the natural particles living in these condensed matter structures, will also obey this defining property of Majorana fermions - that a particle is equal its anti-particle," Prof Kouwenhoven told BBC News. "The system is still built out of atoms, with nuclei and electrons, but the electrons behave together in such a way that their collective state is a Majorana fermion." Other groups working in this field of solid state physics are thought to be close to making similar announcements.
