Supplemental Material for paper : Microscopically - resolved simulations prove the existence of soft cluster crystals

A generic view of the amphiphilic dendrimer architecture, of the effective pair potential and of the hierarchical assembly of the molecules into a cluster crystal is shown in Fig. S1. We employ the dendrimer model already introduced before in Refs. [1, 2] and based on Ref. [3]. We study amphiphilic dendrimers of second generation which have two central monomers. The dendrimers’ 14 monomers are divided into two classes: the eight monomers of the outermost generation (g = 2) form the solvophilic shell of the dendrimer (index S), and all monomers of the interior generations (g = 0 and g = 1) form the solvophobic core (index C), resulting in amphiphilic dendrimers. Interactions between any two monomers, separated by a distance r are modeled by a Morse potential [3], which is given by
