Fig. 5: Active polymers in a porous environment with concave pore shapes.
From: A geometric criterion for the optimal spreading of active polymers in porous media
a Mean-square displacements \(\langle |\Delta{{{\bf{r}}}}_c(t)|^2\rangle\) of active polymers as a function of time for different reversal rates, λτ0, and Péclet number Pe = 50. b Effective diffusivities \({D}_{\,{{{{\mbox{eff}}}}}}^{{{{{\mbox{sim}}}}}}\) as a function of \({\Lambda }={L}_{c,\max }/{\ell }_{{{{\mbox{run}}}}}\). c Slice of the 3D porous environment. Red areas indicate 2D slices of the porous structure and white areas correspond to the open pore space. Source data are provided as a Source Data file.
