Recursion equations in a new approximation in the migdal-kadanoff approach

Рекуррентиье уpaвнения в новом приближении в подходе Мнгдала-Каданова

Il Nuovo Cimento B (1971-1996)

Summary

An alternative to the Kadanoff potential-moving method is proposed and a matching procedure is used to determine the parameters in the transformation. Applications to the 2-, 3-dimensional Ising model yield good estimates of critical couplings and indices.

Riassunto

Si propone un metodo alternativo a quello di Kadanoff per spostare i potenziali; si usa un nuovo procedimento per determinare i parametri della trasformazione. Applicazioni al modello di Ising in 2 e 3 dimensioni danno delle buone stime per gli accoppiamenti e indici critici.

Резюме

Предлагается альтернативный подход для метода Каданова. Для определения параметров преобразования используется процедура подгонки. Применения к двумерной и трехмерной модели Изинга дает хорошие оценки для крит трехмерной модели Изинга дает хорошие оценки для критических связей и индексов. критических связей и индексов.
