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…

Anisotropic Brownian particles under resetting

Subhasish Chaki, Kristian Stølevik Olsen, Hartmut Löwen

We study analytically the dynamics of an anisotropic particle subjected to different stochastic resetting schemes in two dimensions. The Brownian motion of shape-asymmetric particl…

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…

Role of Dissipation on the Stability of a Parametrically Driven Quantum Harmonic Oscillator

Subhasish Chaki, Aranya B Bhattacherjee

We study the dissipative dynamics of a single quantum harmonic oscillator subjected to a parametric driving with in an effective Hamiltonian approach. Using Liouville von Neumann a…

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…

Escape of a passive particle from activity-induced energy landscape: Emergence of slow and fast effective diffusion

Subhasish Chaki, Rajarshi Chakrabarti

Spontaneous persistent motions driven by active processes play a central role to maintain the living cells far from equilibrium. In the majority of the research works, the steady s…

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…

Effects of active fluctuations on energetics of a colloidal particle: superdiffusion, dissipation and entropy production

Subhasish Chaki, Rajarshi Chakrabarti

We consider a colloidal particle immersed in an active bath and derive a Smoluchowski equation that governs the dynamics of colloidal particle. We address this as active Smoluchows…

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…

Entropy production and work fluctuation relations for a single particle in active bath

Subhasish Chaki, Rajarshi Chakrabarti

A colloidal particle immersed in a bath of bacteria is a typical example of a passive particle in an active bath. To model this, we take an overdamped harmonically trapped particle…
