Heterogeneous media diffusion is often described using position-dependent diffusion coefficients and estimated indirectly through mean squared displacement in experiments. This […]
We present an analytical treatment of anomalous diffusion in a three-dimensional comb (xyz-comb) by using the Green’s function approach. We […]
Recent experimental findings on anomalous diffusion have demanded novel models that combine annealed (temporal) and quenched (spatial or static) disorder […]
The comb model is a simplified description for anomalous diffusion under geometric constraints. It represents particles spreading out in a […]
We investigate the solutions, survival probability, and first passage time for a two-dimensional diffusive process subjected to the geometric constraints […]
We investigate the diffusion equation ∂t ρ = Dy ∂y2 ρ + Dx ∂x2 ρ + D ̄xδ(y)∂xμρ subjected to […]
