Web3 de set. de 1999 · The Onsager reaction term is one of the most important notions for frustrated random systems. The role of the Onsager reaction term, however, has not been properly elucidated for non-equilibrium random systems with large degrees of freedoms. By analyzing oscillator associative memory models involving two types of diluted couplings, … Webparameter equations except for the Onsager reaction term. From this, the term is found to lead to a diﬀerence in the rotation speed of the oscillators. This non-trivial phenomenon deﬁnitely shows the contribution of the Onsager reaction term to the acceleration (deceleration) eﬀect. PACS numbers: 87.10.+e, 05.90.+m, 05.45.-a, 89.70.+c
