Effect of polydispersity on the dynamics of active Brownian particles
Sameer Kumar, Jay Prakash Singh, Debaprasad Giri +1
We numerically study the dynamics and the phases of self-propelled disk-shaped particles of different sizes with soft repulsive potential in two dimensions. Size diversity is intro…
Statistical mechanics of a polymer chain attached to the interface of a cone-shaped channel
Sanjay Kumar, Sanjiv Kumar, Debaprasad Giri +1
A polymer chain confined in nano-scale geometry has been used to investigate the underlying mechanism of Nuclear Pore Complex (NPC), where transport of cargoes is directional. It w…
On the rupture of DNA molecule
R. K. Mishra, T. Modi, D. Giri +1
Using Langevin Dynamic simulations, we study effects of the shear force on the rupture of a double stranded DNA molecule. The model studied here contains two single diblock copolym…
Single polymer gating of channels under a solvent gradient
S Nath, D P Foster, D Giri +1
We study the effect of a gradient of solvent quality on the coil-globule transition for a polymer in a narrow pore. A simple self-attracting self-avoiding walk model of a polymer i…
Statistical Mechanics of DNA Rupture: Theory and Simulations
S. Nath, T. Modi, R. K. Mishra +3
We study the effects of the shear force on the rupture mechanism on a double stranded DNA. Motivated by recent experiments, we perform the atomistic simulations with explicit solve…
Scaling of hysteresis loop of interacting polymers under a periodic force
Rakesh Kumar Mishra, Garima Mishra, Debaprasad Giri +1
Using Langevin Dynamics simulations, we study a simple model of interacting-polymer under a periodic force. The force-extension curve strongly depends on the magnitude of the ampli…
