Could anyone please, explain the connection between the Free Energy and the Action?
I know the definitions of each but not sure about the connection.
I read somewhere that the free energy is the same as the action when calculated "on-shell". What does this "on-shell" thing mean in this context?
Thanks a lot in advance!
