Abstract

Clusters in systems as diverse as metal atoms, virus proteins, noble
gases, and nucleons have properties that depend sensitively on the
number of constituent particles. Certain numbers are termed ‘magic’
because they grant the system with closed shells and exceptional
stability. To this point, magic number clusters have been exclusively
found with attractive interactions as present between atoms. Here we
show that magic number clusters exist in a confined soft matter system
with negligible interactions. Colloidal particles in an emulsion droplet
spontaneously organize into a series of clusters with precisely defined
shell structures. Crucially, free energy calculations demonstrate that
colloidal clusters with magic numbers possess higher thermodynamic
stability than those off magic numbers. A complex kinetic pathway is
responsible for the efficiency of this system in finding its minimum
free energy configuration. Targeting similar magic number states is a
strategy towards unique configurations in finite self-organizing systems
across the scales.
