Critical behaviour of the compactified $\lambda {\varphi }^4$ theory

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

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