- 論文の詳細を見る
We introduce a new decoupling method for the configuration averages which appearin the effective field theory for disordered magnets, in order to take into accountpossible spatial correlation of spins in each configuration of the random variables.Using the method we obtain an interpolation scheme between the Edwards-Andersonmodel and the Mattis model, whic:h are the two extremes with respect to the degree ofsuch correlation.
