Electrostatic Persistence Length Revisited. II. Simulations and Comparison to Experiment
Alexey A. Gavrilov, Albert Johner, Artem M. Rumyantsev
For decades, debate has surrounded the electrostatic persistence length (EPL) controlling local polyelectrolyte stiffening, centered on two competing power laws: the linear BJ pred…

Electrostatic Persistence Length Revisited. I. Theory
Artem M. Rumyantsev, Alexey A. Gavrilov, Albert Johner
The problem of single-chain conformations of polyelectrolytes in salt-added dilute solutions, and the associated concept of the electrostatic persistence length $\textbf{l}_\mathrm…

Scaling Law for Sequence-Induced Demixing of Compositionally Identical Copolymers
Artem M. Rumyantsev, Alexey A. Gavrilov
The critical incompatibility of polymers with different compositions scales inversely with their length. For instance, a mixture of A and B homopolymers of length segregates at…
