Majorana fermion
A Majorana fermion is a fermion that is its own antiparticle.
Explanation
Because antineutrinos and neutrinos are neutral particles, it is possible that they are the same particle.
Bound Majorana fermions can appear as quasiparticle excitations.
HistoryThe name of this particle is a tribute to the Italian physicist Ettore Majorana (1906 - 1959 ?). The Dutch physicist Leo Kouwenhoven used this quasiparticle to make a qubit. Warning: The article on this subject in the science journal Nature was withdrawn in 2021. |
