σx|x>=+|x>
σx|-x>=-|-x>
These equations also follows for σy and σz corresponds states |y> and |z>.
if we measure along axis X then X state vector let it go which means up spin and opposite not go through which means down spin.
and also same for y and z axis.
But,
σx|u>=|d> σx|d>=|u>
σy|u>=i|d> σy|d>=-i|u>
σz|u>=|u> σz|d>=-|d>
these 3 equations can't make any sense to me. i can't draw any physical meaning to these equations.
here 1st equation shows if up spin electron goes through along X axis then after measurement spin wilbe down.but this up electron has to be up for any specific axis??right?? without axis up down is unmeaningfull.isn't it??
