Escape rate of transiently active Brownian particle in one dimension
A. Scacchi, J. M. Brader, A. Sharma
Activity significantly enhances the escape rate of a Brownian particle over a potential barrier. Whereas constant activity has been extensively studied in the past, little is known…
Shear-induced migration in colloidal suspensions
P. Marmet, A. Scacchi, J. M. Brader
Using Brownian dynamics simulations we perform a systematic investigation of the shear-induced migration of colloidal particles subject to Poiseuille flow in both cylindrical and p…
Local phase transitions in driven colloidal suspensions
A. Scacchi, J. M. Brader
Using dynamical density functional theory and Brownian dynamics simulations we investigate the influence of a driven tracer particle on the density distribution of a colloidal susp…
Dynamical density functional theory analysis of the laning instability in sheared soft matter
Alberto Scacchi, Andrew J. Archer, Joseph M. Brader
Using dynamical density functional theory (DDFT) methods we investigate the laning instability of a sheared colloidal suspension. The nonequilibrium ordering at the laning transiti…
Mean first passage time of active Brownian particle in one dimension
Alberto Scacchi, Abhinav Sharma
We investigate the mean first passage time of an active Brownian particle in one dimension using numerical simulations. The activity in one dimension is modeled as a two state mode…
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…
