Dynamic Clustering of Active Rings
Ligesh Theeyancheri, Subhasish Chaki, Tapomoy Bhattacharjee +1
A collection of rings made of active Brownian particles (ABPs) for different packing fractions and activities is investigated using computer simulations. We show that active rings…
Active Dynamics of Linear Chains and Rings in Porous Media
Ligesh Theeyancheri, Subhasish Chaki, Tapomoy Bhattacharjee +1
To understand the dynamical and conformational properties of deformable active agents in porous media, we computationally investigate the dynamics of linear chains and rings made o…
Data-driven Discovery of Chemotactic Migration of Bacteria via Machine Learning
Yorgos M. Psarellis, Seungjoon Lee, Tapomoy Bhattacharjee +3
E. coli chemotactic motion in the presence of a chemoattractant field has been extensively studied using wet laboratory experiments, stochastic computational models as well as part…
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…
Confinement and activity regulate bacterial motion in porous media
Tapomoy Bhattacharjee, Sujit S. Datta
Understanding how bacteria move in porous media is critical to applications in healthcare, agriculture, environmental remediation, and chemical sensing. Recent work has demonstrate…
Bacterial hopping and trapping in porous media
Tapomoy Bhattacharjee, Sujit S. Datta
Diverse processes--e.g. bioremediation, biofertilization, and microbial drug delivery--rely on bacterial migration in disordered, three-dimensional (3D) porous media. However, how…
