i am now studying dirac equation and klein paradox
if we confine to one dimension, we only need one alpha matrix, not three
so in lower dimensions, maybe the dirac spinor is not of four components but fewer?
i am curious about this question because it seems that as for the Klein paradox, we have a dimensional problem but the textbooks still work in a three dimensional fashion.
