Simulations and Theories of Single Polyelectrolyte Chains

Arindam Kundagrami, Rajeev Kumar, and Murugappan Muthukumar 

In the light of the above arguments, we present a brief review on the theoretical methods and simulation results. We restrict ourselves to isolated flexible polyelectrolyte chains in solutions. In terms of simulations, we only consider the Langevin dynamics method. For the theory part, we present a variational theory and self-consistent field theory (SCFT), both of which start from an effective Hamiltonian appropriate for flexible charged chains. The background plasma is treated at different levels of sophistication, ranging from the Debye-Hiickel (DH) to the Poisson-Boltzmann descriptions. In this chapter, we have stayed away from less
