@article{Fonseca2019SelfassemblyOC, title={Self-assembly of core-corona particles confined in a circular box}, author={Erik R. Fonseca and Carlos I. Mendoza}, journal={Journal of Physics: Condensed Matter}, year={2019}, volume={32} }
Using Monte Carlo simulations, we study the assembly of colloidal particles interacting via isotropic core-corona potentials in two dimensions and confined in a circular box. We explore the structural variety at low temperatures as function of the number of particles (N) and the size of the confining box and find a rich variety of patterns that are not observed in unconfined flat space. For a small number of particles , we identify the zero-temperature minimal energy configurations at a given…
