TL;DR: In this paper, the global phase diagram for a three-component lattice gas or spin-one Ising model with general single-site and nearest-neighbor "ferromagnetic" interactions is worked out for two-dimensional lattices using a Migdal-Kadanoff recursion relation.

TL;DR: In this article, the authors show that the intrinsic active length scale loses its relevance under strong lateral confinement, and they experimentally and numerically study an active nematic system in confinement finding a defect-free regime of shear flow, and defect nucleation under certain boundary conditions, highlighting the importance of topological defects in controlling confined active flows.

TL;DR: Spatial anisotropy in the domain growth is shown to be a consequence of the flow induced by the changing order parameter field (backflow) and the generalization of the results to the growth of a cylindrical domain, which involves the dynamics of a defect ring, is discussed.

TL;DR: In this article, lattice Boltzmann simulations are used to model the acoustic streaming produced by the interaction of an acoustic wave with a boundary, and deviations from those limits affect the streaming patterns around a cylinder and between two plates of finite length.

TL;DR: In this article, the authors demonstrate that the activity can induce an effective free energy which enhances ordering in extensile systems of active rods and in contractile suspensions of active discs, and that this occurs because any ordering fluctuation is enhanced by the flow field it produces.
