Hello!(adsbygoogle = window.adsbygoogle || []).push({});

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!!!
