A biophysical threshold for biofilm formation
Jenna A. Ott, Selena Chiu, Daniel B. Amchin +2
Bacteria are ubiquitous in our daily lives, either as motile planktonic cells or as immobilized surface-attached biofilms. These different phenotypic states play key roles in agric…
Migration of Active Rings in Porous Media
Ligesh Theeyancheri, Subhasish Chaki, Tapomoy Bhattacharjee +1
Inspired by how the shape deformations in active organisms help them to migrate through disordered porous environments, we simulate active ring polymers in two-dimensional random p…
Influence of confinement on the spreading of bacterial populations
Daniel B. Amchin, Jenna A. Ott, Tapomoy Bhattacharjee +1
The spreading of bacterial populations is central to processes in agriculture, the environment, and medicine. However, existing models of spreading typically focus on cells in unco…
A Geometric Criterion for the Optimal Spreading of Active Polymers in Porous Media
Christina Kurzthaler, Suvendu Mandal, Tapomoy Bhattacharjee +3
We perform Brownian dynamics simulations of active stiff polymers undergoing run-reverse dynamics, and so mimic bacterial swimming, in porous media. In accord with recent experimen…
Chemotactic smoothing of collective migration
Tapomoy Bhattacharjee, Daniel B. Amchin, Ricard Alert +2
Collective migration -- the directed, coordinated motion of many self-propelled agents -- is a fascinating emergent behavior exhibited by active matter that has key functional impl…
