Query: Winding angles for two-dimensional polymers with orientation dependent
  interactions   We study winding angles of oriented polymers with orientation-dependent
interaction in two dimensions. Using exact analytical calculations, computer
simulations, and phenomenological arguments, we succeed in finding the variance
of the winding angle for most of the phase diagram. Our results suggest that
the winding angle distribution is a universal quantity, and that the
$\theta$--point is the point where the three phase boundaries between the
swollen, the normal collapsed, and the spiral collapsed phase meet. The
transition between the normal collapsed phase and the spiral phase is shown to
be continuous.
