Percolation transitions in the binary mixture of active Brownian particles with different softness
Monika Sanoria, Raghunath Chelakkot, Amitabha Nandi
Homogeneous active Brownian particle (ABP) systems with purely repulsive interactions are considered to have simple phase behavior, but various physical attributes of active entiti…
Percolation transition in phase separating active fluid
Monika Sanoria, Raghunath Chelakkot, Amitabha Nandi
The motility-induced phase separation exhibited by active particles with repulsive interactions is well known. We show that the interaction softness of active particles destabilize…
Influence of interaction softness in phase separation of active particles
Monika Sanoria, Raghunath Chelakkot, Amitabha Nandi
Using a minimal model of active Brownian discs, we study the effect of a crucial parameter, namely the softness of the inter-particle repulsion, on motility-induced phase separatio…
Capture of a diffusive prey by multiple predators in confined space
Indrani Nayak, Amitabha Nandi, Dibyendu Das
The first passage search of a diffusing target (prey) by multiple searchers (predators) in confinement is an important problem in the stochastic process literature. While the analo…
Dynamics and stability of contractile actomyosin ring in the cell
Mainak Chatterjee, Arkya Chatterjee, Amitabha Nandi +1
Contraction of the cytokinetic ring during cell division leads to physical partitioning of a eukaryotic cell into two daughter cells. This involves flows of actin filaments and myo…
First passage of a particle in a potential under stochastic resetting: a vanishing transition of optimal resetting rate
Saeed Ahmad, Indrani Nayak, Ajay Bansal +2
First passage in a stochastic process may be influenced by the presence of an external confining potential, as well as "stochastic resetting" in which the process is repeatedly res…
