Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I have recently began studying quatum field theory and have just seen how the quantization of the complex scalar field, noting that there is invariance of the action under a phase rotation shows the existence of antiparticles.

I just have a couple of questions, apologies in advance if they are stupid:

- I'm after some more physical intuition on the phase rotations? I can't find much in a google

- Probably a stupid question: are there any other field types with other in variances that demonstrate the existence of antiparticles in the same way?

Many thanks
