Emergent Isotropic-Nematic Transition in 3D Semiflexible Active Polymers
Twan Hooijschuur, Ehsan Irani, Antoine Deblais +1
Active semiflexible filament collectives, ranging from motor-driven cytoskeletal filaments to slender organisms such as cyanobacteria and worm aggregates, abound in nature. Yet how…
Active motion of tangentially-driven polymers in periodic array of obstacles
Mohammad Fazelzadeh, Ehsan Irani, Zahra Mokhtari +1
We computationally investigate the active transport of tangentially-driven polymers with varying degrees of flexibility and activity in two-dimensional square lattices of obstacles…
Effects of inertia on conformation and dynamics of tangentially-driven active filaments
Mohammad Fazelzadeh, Ehsan Irani, Zahra Mokhtari +1
Active filament-like systems propelling along their backbone exist across the scales ranging from motor-driven bio-filaments to worms and robotic chains. In macroscopic active fila…
Dynamics of bacteria scanning a porous environment
Ehsan Irani, Zahra Mokhtari, Annette Zippelius
It has recently been reported that bacteria, such as E.coli and P. putida, perform distinct modes of motion when placed in porous media as compared to dilute regions or free space.…
Discontinuous shear-thinning in adhesive dispersions
Ehsan Irani, Pinaki Chaudhuri, Claus Heussinger
We present simulations for the steady-shear rheology of a model adhesive dispersion. We vary the range of the attractive forces as well as the strength of the dissipation .…
Athermal rheology of weakly attractive soft particles
Ehsan Irani, Pinaki Chaudhuri, Claus Heussinger
We study the rheology of a soft particulate system where the inter-particle interactions are weakly attractive. Using extensive molecular dynamics simulations, we scan across a wid…
Impact of attractive interactions on the rheology of dense athermal particles
Ehsan Irani, Pinaki Chaudhuri, Claus Heussinger
Using numerical simulations, the rheological response of an athermal assembly of soft particles with tunable attractive interactions is studied in the vicinity of jamming. At small…
