- Help with getting the dirac delta function from the field operator commutation
Hi everyone, I'm taking a QFT course this semester and we're studying from the Otto Nachtman: Texts and Monographs in Physics textbook, today our teacher asked us to get to the equation:
[Φ(x,t),∂/∂tΦ(y,t)]=iZ∂3(x-y)
But I am unsure of how to get to this, does anyone have any advice or any textbooks or notes I could check? Thanks in Advance
