“…Several works about the TUR and quadratic bounds on LD rate functionals have already been produced (see for example [1, 2, 8, 9, 10, 11, 12, 13, 16, 19, 20, 23, This work has been supported by Italian PRIN 20155PAWZB "Large Scale Random Structures" and by the project "Investissements d'Avenir" UCA JEDI of the French ANR n. ANR-15-IDEX-01. 24,26,27,28,29,32,33,34,36,37,38,39,40,41,42] and references therein). In particular, the TUR applies to systems driven by a fixed thermodynamic force.…”
