Abstract
In this paper we try to estimate the louver critical dimension for replica symmetry breaking in spin glasses through the calculation of the additional free-energy required to create a domain wall between two different phases. This mechanism alone would say that replica symmetry would be restored at the louver critical dimension $D_{\rm c} = 2.5$ .
