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. The Dutch physicist Leo Kouwenhoven uses this quasiparticle to make a qubit.

Warning

The article on this subject in the science journal Nature was withdrawn in 2021.

 


Additional information

The name of this particle is a tribute to the Italian physicist Ettore Majorana.
