We study the size R(g) of random polyampholytes (i.e., polymers with randomly charged monomers) as a function of their length N. All results of our extensive Monte Carlo simulations can be rationalized in terms of the scaling theory we develop for the Kantor-Kardar necklace model, although this theory neglects the quenched disorder in the charge sequence along the chain. We find approximately N1/2. The elongated globule model, the initial predictions of both Higgs and Joanny ( approximately N1… CONTINUE READING
