First-order phase transitions in superconducting films: A Euclidean model

C. A. Linhares, A. P. C. Malbouisson, Y. W. Milla +1

In the context of the Ginzburg--Landau theory for critical phenomena, we consider the Euclidean $\lambda {\varphi }^4+\eta {\varphi }^6$ model bounded by two parallel planes, a distance $L$ separating them. Th…
