EFFECTS OF SELF-AVOIDANCE ON THE TUBULAR PHASE OF ANISOTROPIC MEMBRANES

We study the tubular phase of self-avoiding anisotropic membranes. We discuss the renormalizability of the model Hamiltonian describing this phase, and from a renormalization group equation derive some general scaling relations for the exponents of the model. We show how particul ar choices of renormalization factors reproduce the Gaussian result, t he Flory theory, and the Gaussian variational treatment of the problem . We then study the perturbative renormalization to one loop in the se lf-avoiding parameter using dimensional regularization and an epsilon expansion about the upper critical dimension, and determine the critic al exponents to first order in epsilon.
