On the origin of super-diffusive behavior in a class of non-equilibrium systems
Himadri S. Samanta, D. Thirumalai
Experiments and simulations have established that dynamics in a class of living and abiotic systems that are far from equilibrium exhibit super diffusive behavior at long times, wh…
Charge fluctuation effects on the shape of flexible polyampholytes with applications to Intrinsically disordered proteins
Himadri S. Samanta, Debayan Chakraborty, D. Thirumalai
Random polyampholytes (PAs) contain positively and negatively charged monomers that are distributed randomly along the polymer chain. The interaction between charges is assumed to…
Giant Casimir non-equilibrium forces drive coil to globule transition in polymers
Himadri S. Samanta, Mauro L. Mugnai, T. R. Kirkpatrick +1
We develop a theory to probe the effect of non-equilibrium fluctuation-induced forces on the size of a polymer confined between two horizontal thermally conductive plates subject t…
Optimal information transfer in enzymatic networks: A field theoretic formulation
Himadri S. Samanta, Michael Hinczewski, D. Thirumalai
Signaling in enzymatic networks is typically triggered by environmental fluctuations, resulting in a series of stochastic chemical reactions, leading to corruption of the signal by…
Exact solution of the Zwanzig-Lauritzen model of Polymer Crystallization under Tension
Himadri S Samanta, D. Thirumalai
We solve a two dimensional model for polymer chain folding in the presence of mechanical pulling force () exactly using equilibrium statistical mechanics. Using analytically der…
Resonance and limit cycle in a noise driven Lorenz model
Himadri S. Samanta, J. K. Bhattacharjee
The effect of an external noise on the Lorenz model is investigated near the onset of convection and near the Hopf bifurcation. We show the existence of a diverging time scale near…
