摘要：
在低温下，超软粒子系统通过粒子团簇的自组装形成引人关注的相。本研究开展了通用的零温分析，在限定每个团簇包含恒定整数个粒子的经典系统前提下，完整表征了这类模型在二维和三维下的基态。我们表明，该方法可精确预测不同相出现的实际密度值，包括团簇占据数不均的区域——这类区域被作为两种纯相的共存区加以研究。除了这套旨在从通用超软势生成精确相图的方法本身，我们还得到了大占据极限下不同相的能量与位置的解析表达式。
英文摘要：
At low temperatures ultrasoft particle systems develop interesting phases via the self-assembly of particle clusters. In this study we develop a general zero-temperature analysis fully characterizing the ground state of such models in two and three dimensions, considering the classical system with the restriction of a constant integer number of particles per cluster. We show that this methodology allows for an exact prediction of the actual density values at which the different phases emerge, including the zones of uneven cluster occupation, which are studied as coexistence regions of two pure phases. Beyond the method itself, designed to produce exact phase diagrams from general ultrasoft potentials, we reach analytical expressions for the energy and location of the different phases in the large occupancy limit.
