title: Bethe approximation for a DNA-like self-avoiding walk model with variable solvent quality.
abstract: The phase diagram and critical behavior of a simple toy model for DNA zipping/unzipping are examined in the framework of the Bethe approximation. The effects of solvent quality are included and found to lead to a variety of different thermodynamic behaviors.
