概要

• 論文の詳細を見る

• A new critical exponent associated with impurity effect is introduced in the case of wave-number dependent susceptibility G(q) at T=T_c. The G(q) is expanded up to a^2 (a is a parameter representing the strength of impurity effect) and is shown to take a form G(q)=Aq^<-2+η>+Bq^<-2+ηi>. An exponent η_i is studied in the limit n→∞ and also up to ε^2 in the scheme of ε expansion for the quenched system. It turns out that the results obtained by two methods are consistent.
