Translational and Rotational Temperature Difference in Coexisting Phases of Inertial Active Dumbbells
Subhasish Chaki, Hartmut Löwen
We investigate the effect of translational and rotational inertia on motility-induced phase separation in underdamped active dumbbells and identify the emergence of four distinct k…
Theoretical Analysis of the Structure, Thermodynamics, and Shear Elasticity of Deeply Metastable Hard Sphere Fluids
Subhashish Chaki, Baicheng Mei, Kenneth S. Schweizer
The structure, thermodynamics and slow activated dynamics of the equilibrated metastable regime of glass-forming fluids remains a poorly understood problem of high theoretical and…
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…
Reconfiguration, swelling and tagged monomer dynamics of a single polymer chain in Gaussian and non-Gaussian active baths
Koushik Goswami, Subhasish Chaki, Rajarshi Chakrabarti
In this topical review, we give an overview of the structure and dynamics of a single polymer chain in active baths, Gaussian or non-Gaussian. The review begins with the discussion…
A Polymer Chain with Dipolar Active Forces in Connection to Spatial Organization of Chromatin
Subhasish Chaki, Ligesh Theeyancheri, Rajarshi Chakrabarti
A living cell is an active environment where the organization and dynamics of chromatin are affected by different forms of activity. Optical experiments report that loci show subdi…
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…
Translational and rotational dynamics of a self-propelled Janus probe in crowded environments
Ligesh Theeyancheri, Subhasish Chaki, Nairhita Samanta +3
We computationally investigate the dynamics of a self-propelled Janus probe in crowded environments. The crowding is caused by the presence of viscoelastic polymers or non-viscoela…
Transport of probe particles in polymer network: effects of probe size, network rigidity and probe-polymer interaction
Praveen Kumar, Ligesh Theeyancheri, Subhasish Chaki +1
Fundamental understanding of the effect of microscopic parameters on the dynamics of probe particles in different complex environments has wide implications. Examples include diffu…
Enhanced diffusion, swelling and slow reconfiguration of a single chain in non-Gaussian active bath
Subhasish Chaki, Rajarshi Chakrabarti
A prime example of non-equilibrium or active environment is a biological cell. In order to understand in-vivo functioning of biomolecules such as proteins, chromatins, a descriptio…
