Inequivalence of fixed-force and fixed-extension statistical ensembles for a flexible polymer tethered to a planar substrate
Sandipan Dutta, Panayotis Benetatos
Recent advances in single macromolecule experiments have sparked interest in the ensemble dependence of force-extension relations. The thermodynamic limit may not be attainable for…
Effective potentials in polyelectrolyte solutions
Sandipan Dutta, and Y. S. Jho
Using Poisson-Boltzmann equation and linear response theory, we derive an effective interaction potential due to a fixed charge distribution in a solution containing polyelectrolyt…
Adsorption of highly charged Gaussian polyelectrolytes to oppositely charged surfaces
Sandipan Dutta, Y. S. Jho
In many biological processes highly charged biomolecules are adsorbed into oppositely charged surfaces of macroions and membranes. They form strongly correlated structures close to…
Strong coupling electrostatic theory of polymer counterions close to planar charges
Sandipan Dutta, Y. S. Jho
Strong coupling phenomena, such as the like charged macroions attraction, opposite charged macroions repulsion, charge renormalization or charge inversion, are known to be mediated…
Bundle formation in parallel aligned polymers with competing interactions
Sandipan Dutta, P. Benetatos, Y. S. Jho
Aggregation of like-charged polymers is widely observed in biological and soft matter systems. In many systems, bundles are formed when a short-range attraction of diverse physical…
Shell formation in short like-charged polyelectrolytes in a harmonic trap
Sandipan Dutta, Y. S. Jho
Inspired by recent experiments and simulations on pattern formation in biomolecules by optical tweezers, a theoretical description based on reference interaction site model (RISM)…
