N2 - We quantitatively investigate the behavior of momentum cumulants in the φ{symbol}4 theory under thermal gradients, using stochastic thermostats. We relate this to the violations of local equilibrium. The non-equilibrium behavior is found to be quite well described by a dependence ∼ (∇ T)2, on the temperature gradient. Dependence of the quantities on the thermostat type is analyzed and its physical implications are discussed.
