Solutions to the Klein-Gordon equation can be interpreted as spin-0 particles of mass m and charge +1, 0, -1? See here. I think same can be said for solutions to the Dirac equation in 1+1 dimensional space-time, solutions can be interpreted as spin-0 particles of mass m and charge +1, 0, -1? Solutions for the Dirac equation in 1+1D involve spinors but not solutions to the Klein-Gordon equation in 1+1D, what gives? It seems like the same "stuff" is represented in 2 equivalent ways?(adsbygoogle = window.adsbygoogle || []).push({});

Thanks for any help!
