Question ?: Show that |+ } = (A) and | } = ('1') are Eigneetatee for the operator E2, and that the . . . . . corresponding Eigenvalues are :3 . Use the matrix representations QIVQH above. CO = 1 = of = hi h h h O also S = and Sy = N 2 2 + We can write spin up in many ways, including: "spin up" = a = [ 1 ) = + 7 ) = 10 ) = 1+> = (0) and, likewise, for spin down: "spin down" = P = | 4 ) = - = IB) = 1 -) = The column matrices are called the matrix representations of the two spin states. They are useful when dealing with the matrix representations of the operators
