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…
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…
