We analyze the percolation properties of certain clusters defined on configurations of the 2–dimensional Heisenberg model. We find that, given any direction n → → 𝑛 \vec{n} over→ start_ARG italic_n end_ARG, in O (3) 𝑂 3 O(3) italic_O ( 3 ) space, the spins almost perpendicular to n → → 𝑛 \vec{n} over→ start_ARG italic_n end_ARG form a …
