Corrections to scaling in multicomponent polymer solutions

Abstract

We calculate the correction-to-scaling exponent ${\omega }_T$ that characterizes the approach to the scaling limit in multicomponent polymer solutions. A direct Monte Carlo determination of ${\omega }_T$ in a system of interacting self-avoiding walks gives ${\omega }_T=0.415(20)$. A field-theory analysis based on five- and six-loop perturbative series leads to ${\omega }_T=0.41(4)$. We also verify the renormalization-group predictions for the scaling behavior close to the ideal-mixing point.
