Web21 mrt. 2024 · Based on the Dirac spinor representation of the SO(4) group, we discuss the relationship between three types of representation of spin in terms of Majorana fermions, namely the Kitaev representation, the SO(3) representation, and the SO(4) chiral representation. Comparing the three types, we show that the Hilbert space of the … WebThere are many equivalent ways to write this representation as 4 4 matrices. The best-known ones are the Dirac, Weyl and Majorana representations. These are often presented in the form of 2 2 matrices whose elements are again 2 2 matrices.
