i am now studying dirac equation and klein paradox(adsbygoogle = window.adsbygoogle || []).push({});

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.
