The study of active soft matter has developed into one of the most rapidly growing areas of
physics. Field theories, which can be developed either via phenomenological …

We consider a non-reciprocally coupled two-field Cahn–Hilliard system that has been
shown to allow for oscillatory behaviour and suppression of coarsening. After introducing the …

Classical dynamical density functional theory (DDFT) has become one of the central
modeling approaches in nonequilibrium soft matter physics. Recent years have seen the …

We introduce a family of lattice-gas models of flocking, whose thermodynamically consistent
dynamics admits a proper equilibrium limit at vanishing self-propulsion. These models are …

While the collective dynamics of spherical active Brownian particles is relatively well
understood by now, the much more complex dynamics of nonspherical active particles still …

We demonstrate that several nonvariational continuum models commonly used to describe
active matter as well as other active systems exhibit nongeneric behavior: each model …

We consider a class of continuum models with a spurious gradient dynamics structure that
form a bridge between passive and active systems: They formally maintain variational …

Liquid crystals consisting of biaxial particles can exhibit a much richer phase behavior than
their uniaxial counterparts. Usually, one has to rely on simulation results to understand the …

The worldwide COVID-19 pandemic has led to a significant growth of interest in the
development of mathematical models that allow to describe effects such as social distancing …

While the collective dynamics of spherical active Brownian particles is relatively well
understood by now, the much more complex dynamics of nonspherical active particles still …
