Is the wave function for the positron the complex conjugate of the wave function for the electron? I've tried to google this, but I can't seem to get a definite answer from a reliable source. It seems that antimatter is derived in quantum field theory which does not concentrate on wave functions. And there the charge is conjugated, which amounts to taking the complex conjugate. But then I'm told that you can look at the positron as if it were an electron moving backwards in time. The negative sign on the time variable can be shifted to a negative sign on the complex i, which gives us a complex conjugate. But a wave function can describe motion through time and space, so I suppose you'd have to assume that the positron was moving with the same momentum as the electron. Then is the wave function of the positron the complex conjugate of the electron? Thanks.
