We study the stationary dynamics of an active interacting Brownian particle system. We
measure the violations of the fluctuation dissipation theorem, and the corresponding …

Self-propelled particles in anisotropic environments can exhibit a motility that depends on
their orientation. This dependence is relevant for a plethora of living organisms but difficult to …

Self-alignment describes the property of a polar active unit to align or anti-align its
orientation towards its velocity. In contrast to mutual alignment, where the headings of …

We study the two-dimensional Langevin dynamics of a mixture of two types of particles that
live respectively at two different temperatures. Dynamics is constrained by an optical trap …

We study in this work the two-dimensional dynamics of an experimental system of disk-
shaped rotors, fluidized by turbulent upflow. Contrary to previous knowledge, our …

We study a class of two-dimensional models of classical hard-core particles with Vicsek type
“exchange interaction” that aligns the directions of motion of nearby particles. By extending …

Aggregative life cycles are characterized by alternating phases of unicellular growth and
multicellular development. Their multiple, independent evolutionary emergence suggests …

We study long-range order in two dimensions where an order parameter is advected by
linear laminar flows. The linear laminar flows include three classes: rotational, shear, and …

We consider a class of non-standard, two-dimensional (2D) Hamiltonian models that may
show features of active particle dynamics, and therefore, we refer to these models as active …

We investigate the impact of the boundary shape on the thermalization behavior of a
confined system of classical hard disks at low packing fraction and thus in the gas regime …
