Taking the derivative $\partial S /\partial \overline{E}$ is 100% a mistake that accidentally gives the right answer. It works without having to take it: $$ \begin{align} S(\beta)&=\ln Z(\beta) +...

A QFT can be constructed as $$Z[J] \propto \int e^{iS[\phi]+J.\phi} D[\phi]$$ because $$ e^{iS+J} = e^Je^{iS}=e^J(\cos S + i \sin S) $$ The real part of the exponential simply represents the ...
