Majorana

Part of speech: noun

Definitions

1. A type of particle that is its own antiparticle, which is significant in quantum physics
2. Referring to theoretical particles proposed by Ettore Majorana in the context of particle physics and quantum theory
3. Pertaining to a class of fermions that exhibit both particle and antiparticle characteristics, crucial for advanced physics discussions

Etymology: Ettore Majorana was an Italian physicist from Sicily who vanished in 1938, at the age of 31, after buying a ticket by ship from Palermo to Naples and never being seen again. His name, which the word takes, is an Italianized form of the Sicilian surname Majurana. That surname is itself derived from "majurana", the Sicilian word for marjoram, the aromatic herb. So a term now used in quantum theory traces back to a kitchen plant, passed down through a family name. The particles that bear his name were proposed in 1937, when Majorana argued that a fermion could be its own antiparticle. Such particles are now called Majorana fermions. The concept is theoretical, and physicists have sought them in experiments, notably in certain superconducting and nanowire systems, where they might serve as building blocks for fault-tolerant quantum computing.
