Majorana is a term that is specific to particle physics and refers to a type of particle known as Majorana fermions. These are unique because they are their own antiparticle. While there are not many synonyms for Majorana in the conventional sense, some related terms in physics include Majorana quasiparticles and Majorana modes. These are similar in nature to Majorana fermions and can help to enhance our understanding of their properties and behavior. Other synonyms for Majorana might include phrases like "self-conjugate particle" or "own-antiparticle particle," however, these are not common alternatives in scientific or technical contexts.
