Many complex fluids can be described by continuum hydrodynamic field equations, to which noise must be added in order to capture thermal fluctuations. In almost all cases, the resulting coarse-grained stochastic partial differential equations carry a

The hallmark of active matter is the autonomous directed motion of its microscopic constituents driven by consumption of energy resources. This motion leads to the emergence of large-scale dynamics and structures without any equilibrium equivalent. T

We develop a minimal model to describe growing dense active matter such as biological tissues, bacterial colonies, and biofilms, which are driven by a competition between particle division and steric repulsion. We provide a detailed numerical analysi

The swimming of cells, far from any boundary, can arise in the absence of long-range liquid-crystalline order within the cytoplasm, but simple models of this effect are lacking. Here, we present a two-dimensional model of droplet self-propulsion invo

Many biological systems, such as bacterial suspensions and actomyosin networks, form polar liquid crystals. These systems are ‘active’ or far-from-equilibrium, due to local forcing of the solvent by the constituent particles. In many cases the so

It is known that purely repulsive self-propelled colloids can undergo bulk liquid-vapor phase separation. In experiments and large-scale simulations, however, more complex steady states are also seen, comprising a dynamic population of dense clusters

Active-matter systems operate far from equilibrium because of the continuous energy injection at the scale of constituent particles. At larger scales, described by coarse-grained models, the global entropy production rate S quantifies the probability

It has been known that the motion of self-propelled particles inside an asymmetric channel can be rectified to give rise to a macroscopic and unidirectional current. In this paper, we show that division and apoptosis process alone (which are ubiquito

In passive fluid-fluid phase separation, a single interfacial tension sets both the capillary fluctuations of the interface and the rate of Ostwald ripening. We show that these phenomena are governed by two different tensions in active systems, and c
