Using a minimal model based on the continuum theory of a two-dimensional hard-core/square-shoulder ensemble, we reinterpret the main features of cluster mesophases formed by colloids with soft shoulder-like repulsive interactions. We rederive the lattice spacing, the binding energy, and the phase diagram. We also extend the clustering criterion [Likos, C. N. et al. Phys. Rev. E, 2001, 63, 031206; Glaser, M. A. et al. EPL2007, 78, 46004] to include the effect of the hard cores, which precludes the formation of clusters at small densities.
利用基于二维硬球/方肩集合体连续体理论的最小模型，我们重新解释了具有软方肩排斥相互作用的胶体形成的聚集体中间相的主要特征。我们重新推导了晶格间距、结合能和相图。我们还扩展了聚类判据[Likos，C. N.等。物理评论 E，2001，63，031206；Glaser，M. A.等。EPL2007，78，46004]以包括硬核心的影响，这阻止了在小密度下形成聚集体。
