Pair interactions between active particles need not follow Newton's third law. In this work, we
propose a continuum model of pattern formation due to nonreciprocal interaction between …

In active matter, particles typically experience mediated interactions, which are not
constrained by Newton's third law and are therefore generically non-reciprocal. Non …

Population heterogeneity is ubiquitous among active living systems, but little is known about
its role in determining their spatial organization and large-scale dynamics. Combining …

Heterogeneity is ubiquitous in biological and synthetic active matter systems that are
inherently out of equilibrium. Typically, such active mixtures involve not only conservative …

Extensive studies so far have indicated that chirality, anisotropic interactions and spatial
confinement play important roles in collective dynamics in active matter systems. However …

We consider microscopic models of active particles whose velocities, rotational diffusivities,
and tumbling rates depend on the gradient of a local field that is either externally imposed or …

We study active surface wetting using a minimal model of bacteria that takes into account the
intrinsic motility diversity of living matter. A mixture of “fast” and “slow” self-propelled …

Transport coefficients like shear, bulk and longitudinal viscosities are sensitive to the
intermolecular interaction potential and finite size effects when are numerically determined …

We study quasi two-dimensional, monodisperse systems of active Brownian particles (ABPs)
for a range of activities, stiffnesses, and densities. We develop a microscopic, analytical …

Artificial micro/nanomotors are expected to perform tasks in interface-rich and species-rich
environments for biomedical and environmental applications. In these highly confined and …
