Critical behaviour of the compactified $λ ϕ^{4}$ theory

L. M. Abreu, C. de Calan, A. P. C. Malbouisson +2

We investigate the critical behaviour of the $N$ -component Euclidean $λ ϕ^{4}$ model at leading order in $\frac{1}{N}$ -expansion. We consider it in three situations: confined between…

Halperin-Lubensky-Ma effect in type-I superconducting films

L. M. Abreu, C. de Calan, A. P. C. Malbouisson

In this note we employ concurrently techniques of generalized $z e t a$ -functions and compactification methods introduced in previous publications, to study the Halperin-Lubensky-Ma t…

Critical behavior of YBa_{2}Cu_{3}O_{7-δ} and Bi_{2}Sr_{2}CaCu_{2}O_{8+δ} from the dual Ginzburg-Landau model

Claude de Calan, Flavio S. Nogueira

An unifying scenario for the critical behavior of YBa $_{2}$ Cu $_{3}$ O $_{7 - δ}$ (YBCO) and Bi $_{2}$ Sr $_{2}$ CaCu $_{2}$ O $_{8 + δ}$ (BSCCO) is proposed. It is shown that both critical cros…
