Effective equilibrium states in mixtures of active particles driven by colored noise
René Wittmann, Joseph M. Brader, Abhinav Sharma +1
We consider the steady-state behavior of pairs of active particles having different persistence times and diffusivities. To this purpose we employ the active Ornstein-Uhlenbeck mod…
Phase diagram of two-dimensional hard rods from fundamental mixed measure density functional theory
René Wittmann, Christoph E. Sitta, Frank Smallenburg +1
A density functional theory for the bulk phase diagram of two-dimensional orientable hard rods is proposed and tested against Monte Carlo computer simulation data. In detail, an ex…
Active Brownian particles at interfaces: An effective equilibrium approach
René Wittmann, Joseph M. Brader
A simple theoretical approach is used to investigate active colloids at the free interface and near repulsive substrates. We employ dynamical density functional theory to determine…
Effective equilibrium states in the colored-noise model for active matter II. A unified framework for phase equilibria, structure and mechanical properties
René Wittmann, Umberto Marini Bettolo Marconi, Claudio Maggi +1
Active particles driven by colored noise can be approximately mapped onto a system that obeys detailed balance. The effective interactions which can be derived for such a system al…
Effective equilibrium states in the colored-noise model for active matter I. Pairwise forces in the Fox and unified colored noise approximations
René Wittmann, Claudio Maggi, Abhinav Sharma +3
The equations of motion of active systems can be modeled in terms of Ornstein-Uhlenbeck processes (OUPs) with appropriate correlators. For further theoretical studies, these should…
