Critical Casimir effect in a disordered $O (2)$ -symmetric model

G. O. Heymans, N. F. Svaiter, B. F. Svaiter +1

Critical Casimir effect appears when critical fluctuations of an order parameter interact with classical boundaries. We investigate this effect in the setting of a Landau-Ginzburg…

The vacuum energy with non-ideal boundary conditions via an approximate functional equation

E. Arias, G. O. Heymans, H. T. Lopes +1

We discuss the vacuum energy of a quantized scalar field in the presence of classical surfaces, defining bounded domains $Ω \subset R^{d}$ , where the field satisfies idea…
