Eigenkets of the field operator.

[TriTertButoxy]

I'm doing a calculation in QFT and in order to proceed, I need to know the eigenkets of the field operator (say the scalar field for example).

Where can I look to find the eigenkets. Or, if anyone knows, could you post it?

Thanks!

Thanks!Are you still wondering about this?
