2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/231421We show how a chiral Dirac fermion (a massless electron or hole) can be converted into a pair of neutral chiral Majorana fermions (a particle equal to its own antiparticle). These two types of fermions exist on the metallic surface of a topological insulator, respectively, at a magnetic domain wall and at a magnet-superconductor interface. Interferometry of Majorana fermions is a key operation in topological quantum computation, but the detection is problematic since these particles have no charge. The Dirac-Majorana converter enables electrical detection of the interferometric signal.4 pages, 2 figuresMesoscale and Nanoscale PhysicsSuperconductivityQuantum Physicstext
