Hello!
I met some annoying problems on quantum field operators in QFT.They are as follows:
(1)The quantum field operator( scalar field operator, for example),is often noted as
φ(r,t). Can it be interpreted as like this: φ(r,t) is the coordinate represetation of a
more abstract,theoretical operator φ in Hilbert space?
(2)Is there exist the represetation(such as momentum, coordinate...) which is similar to
that in quantum mechanics in QFT?
Thanks for reply!
