Simulations of colloidal systems

Colloids consist of mesoscopic particles, typically a few hundred nanometers in size, dispersed in a fluid and subjected to thermal fluctuations. Due to the tunability of their interactions, these soft-matter systems provide a versatile platform for studying diverse physical phenomena in Condensed Matter Physics. Once crucial in probing the discrete nature of matter and later regarded as analogs of atomic systems, colloidal systems have since established themselves as an intriguing form of matter, continuing to drive scientific curiosity. Their ability to self-assemble into functional soft materials also makes them promising building blocks for nanotechnology with broad practical applications. Understanding and predicting their behavior is therefore crucial, and computational modeling has become indispensable in this endeavor. This chapter reviews widely used multiscale models and simulation methods for the computational study of colloidal materials.
