Bo Söderberg Polymers, Spin Models and Field Theory In proc.: H. Meyer-Ortmanns, A. Klümper (eds.), Field Theoretical Tools for Polymer and Particle Physics, (Springer Verlag, Berlin 1998). Abstract: The generic relation between continuous polymers and zero-component Euclidean field-theories is reviewed, and exemplified by polymers with contact and Coulomb interactions. An analogous relation on the lattice is also discussed, relating the statistics of self-avoiding walks to a zero-component spin-model. LU TP 97-25
