- I had been trying to understand second quantization for few months from an easy book "Quantum Field Theory Demystified". But couldn't succeed. So, I have posted my problem.
I understand how do 3 no. equation come from 1 & 2 no. equation. But I am struggling to understand how do 4 no. equation come from 3 no. equation. Will anyone do the steps between 3 no. equation and 4 no. equation, please ?
