The study of self-assembly of colloidal particles under confinement using Langevin dynamics

One of the topics popular in the field of soft matter is the self-assembling phenomena in which the ordering appears in the system without microscopic manipulation of system components. The self-assembly of colloidal particles is also actively researched in this trend. The recent advance in self-assembly of colloidal particles is the self-assembly under spherical confinement in the work of De Nijs et al. in 2014. We investigated diverse aspects of self-assembling phenomena from confinement and discovered new geometry appears in the system with Langevin dynamics using the well-known molecular dynamics package, LAMMPS. The new geometry is also observed in experiment too and its appearance and stability are discussed in the analysis of thermodynamics.
