The potential for matter to self-assemble in complex morphologies and to follow intricate dynamics is of great fundamental interest as well as for a broad array of applications in nanotechnology, catalysis, drug delivery, and beyond. The inherent complexity of these processes, however, is a challenge both to theories and to numerical simulations. This talk focuses on two such complex systems: (i) equilibrium microphases and (ii) out-of-equilibrium active matter. In the first part, a model of microphase formers with short-range attractive and long-range repulsive (SALR) interactions is investigated, and the relevant Monte Carlo methods are evaluated and developed. In the second part, the out-of-equilibrium nature of active matter is confronted with the goal of obtaining first-principle descriptions of its behavior. A single-particle model of an active Brownian particle (ABP) is studied with dimension approaching to infinity, and new insight has been obtained, which helps chart the way for eventually solving dynamic mean-field theory.
