This lead people to confuse them with Majorana fermions of high energy physics, these two are very different objects. For example in high energy physics Majorana fermions ARE fermions, while in condensed matter physics they are not (this IS the reason why we are so interested in them in the first place). There are of course some work which describe these anyons as true fermions coupled to a BF-theory, and the non-abelian nature pops out after integrating out the BF-gauge fields.<br /><br />However, I still believe that people stretch the analogy way too far by comparing Majorana fermions of high energy physics, and condensed matter physics. You could also call mesons for "Room Temp. superconductors", then say "1 - 0 to high energy physics since they found a Room Temp. superconductor". Its just a name, it doesn't say the physics is similar at all.HMhttps://www.blogger.com/profile/15133711515963714923noreply@blogger.com
