We prove that, in the \u201cintermittent regime\u201d: (1) If the equation is sufficiently noisy, then the resulting stochastic PDE has a unique invariant measure; and (2) If the equation is in a low-noise regime, then there are infinitely many invariant measures and the collection of all invariant measures is a line segment in path space. This gives proof to earlier predictions of Zimmerman et al (2000), discovered first through experiments and computer simulations.<br \/>\nThis is joint work with Carl Mueller (University of Rochester)
