Topotaxis of Active Particles Induced by Spatially Heterogeneous Sliding along Obstacles
Zeinab Sadjadi, Heiko Rieger
Many biological active agents respond to gradients of environmental cues by redirecting their motion. Besides the well-studied prominent examples such as photo- and chemotaxis, the…
Orientational Memory of Active Particles in Multistate Non-Markovian Processes
Zeinab Sadjadi, M. Reza Shaebani
The orientational memory of particles can serve as an effective measure of diffusivity, spreading, and search efficiency in complex stochastic processes. We develop a theoretical f…
Persistent-random-walk approach to anomalous transport of self-propelled particles
Zeinab Sadjadi, M. Reza Shaebani, Heiko Rieger +1
The motion of self-propelled particles is modeled as a persistent random walk. An analytical framework is developed that allows the derivation of exact expressions for the time evo…
Anomalous Diffusion of Self-Propelled Particles in Directed Random Environments
M. Reza Shaebani, Zeinab Sadjadi, Igor M. Sokolov +2
We theoretically study the transport properties of self-propelled particles on complex structures, such as motor proteins on filament networks. A general master equation formalism…
Anomalous Front Broadening During Spontaneous Imbibition in a Matrix with Elongated Pores
Simon Gruener, Zeinab Sadjadi, Helen E. Hermes +4
During spontaneous imbibition a wetting liquid is drawn into a porous medium by capillary forces. In systems with comparable pore length and diameter, such as paper and sand, the f…
Diffusive transport of light in three-dimensional disordered Voronoi structures
Zeinab Sadjadi, MirFaez Miri, Holger Stark
The origin of diffusive transport of light in dry foams is still under debate. In this paper, we consider the random walks of photons as they are reflected or transmitted by liquid…
Diffusive transport of light in a two-dimensional disordered packing of disks: Analytical approach to transport-mean-free path
Zeinab Sadjadi, MirFaez Miri, M. Reza Shaebani +1
We study photon diffusion in a two-dimensional random packing of monodisperse disks as a simple model of granular media and wet foams. We assume that the intensity reflectance of d…
