Abstract: | |||||
We have studied the transition in shape of two dimensional
polyampholytes using Monte Carlo simulation. We observe that
polymers with randomly charged monomers get into a globular shape
at lower temperatures, provided that their total charge is below a
critical value Qc. Collapse into globular form happens for
all forms of force law, but the critical charge depends on the
form of the force law, inversely dependent on the range of
interaction.
