WebDerive formulae which determine the effect of the spin operator on a vector wave function of a particle with spin 1. Solution. The relation between the components of the vector function Ψ and the components of the spinor ψ λμ is given by formulae (57.9), and from (57.5) we have. (where ψ ± = ψ x ± i ψ y) or. The space of spinors is formally defined as the fundamental representation of the Clifford algebra. (This may or may not decompose into irreducible representations.) The space of spinors may also be defined as a spin representation of the orthogonal Lie algebra. These spin representations are also characterized as the finite-dimensional projective representations of the speci…
