Abstract

In this talk we discuss a two-dimensional directed self-avoiding walk model of a random copolymer in a random emulsion. The copolymer is a random concatenation of monomers of two types, A and B, each occurring with density 12. The emulsion is a random mixture of liquids of two types, A and B, organised in large square blocks occurring with density p and 1p, respectively, where p(0,1). The copolymer in the emulsion has an energy that is minus α times the number of AA-matches minus β times the number of BB-matches. We will consider both the supercritical regime (oil droplets form an infinite cluster) and the subcritical regime (no infinite cluster).
