| Jul 6, 2020 at 15:33 | comment | added | Carlo Beenakker | I mean to derive the field theory from a Hamiltonian -- how is $\phi$ related to microscopic degrees of freedom? | |
| Jul 6, 2020 at 15:01 | comment | added | JustWannaKnow | @CarloBeenakker thanks for the reference! What do you mean by 'derive this from some physical model'? You mean choosing the right covariance so it represents some physical model? | |
| Jul 2, 2020 at 15:24 | comment | added | Carlo Beenakker | a definition of the continuous GFF along the lines of your Q1-Q5 is Generalized random fields and Lévy's continuity theorem on the space of tempered distributions; from the mathematical side the Euclidean path integral is perfectly well defined, the difficult nontrivial task is to derive this from some physical model. | |
