Hello all quantum nerds! :D
I have a question regarding the "classical" limit of quantum fields, and in particular gauge fields. When we for instance do a surface integration in QFT, we let phi > 0 as V>oo why? this is said in textbooks to correspond to the "classical limit", and for gauge fields, one lets the field strength tensor F_mu,nu > 0 which makes the gauge potential go to zero or a gauge transformation of 0. So why these boundaries in the "classical" limit (V>oo) Best regards
