“…Heat transport in long-range models exhibits quite interesting and peculiar features, that depend on the nature of the interaction potential. The comparison between the rotor chain and the FPU-β chain confirms this scenario, that was already outlined in some recent pubblications [5][6][7]. In this paper we have shown that in the non-additive regime corresponding to 0 < α < 1 the mechanism of heat transport is dominated by the direct, mean-field like contribution, irrespectively of the kind of the interaction potential.…”

“…What should we expect when two or more external reservoirs drive a long-range interacting system in out-ofequilibrium conditions? Some peculiar features, pointed out in a recent paper by Avila et al [5] have been confirmed and more systematically investigated in a longrange coupled rotor chain [6]. This model is quite interesting, because for nearest-neighbor (i.e.…”

“…A discussão sobre algumas propriedades do Capítulo 3. O papel das correlações entre as velocidades nos perfis de temperatura do sistema 49 fluxo de calor em cadeias não lineares possui uma vasta literatura associada a resultados obtidos via simulação numérica [25,26,[66][67][68], enquanto o tratamento analítico para este tipo de modeloé abordado por poucos autores [69][70][71]. Para ilustrar um dos impactos das não linearidades sobre o sistema original, mostra-se na figura 3.8 o que ocorre com as correlações entre as velocidades quando introduz-se um termo cúbico de interação entre as partículas.…”
