Web1 dag geleden · Other topics include symmetry in quantum field theories, a relativistic 10-fold way, the homotopy theory of relativistic free fermions, and a topological spin-statistics theorem. Majorana bound states in quantum error correction. One of the causes of interest in Majorana bound states is that they could be used in quantum error correcting codes. This process is done by creating so called 'twist defects' in codes such as the toric code which carry unpaired Majorana modes. Meer weergeven A Majorana fermion , also referred to as a Majorana particle, is a fermion that is its own antiparticle. They were hypothesised by Ettore Majorana in 1937. The term is sometimes used in opposition to a Dirac fermion, … Meer weergeven Because particles and antiparticles have opposite conserved charges, Majorana fermions have zero charge, hence among the … Meer weergeven • Pal, Palash B.

WebUniversity of Groningen WebMajorana’s colleagues described him as humble because he considered some of his work unexceptional. For example, Majorana correctly predicted in 1932 the existence of the neutron, which he dubbed a neutral proton, based on an atomic-structure experiment by Irène Joliot-Curie and Frédéric Joliot-Curie.
