I will describe joint work with Jared Wunsch on propagation of singularities for some semiclassical Schrödinger equations where the potential is conormal to a hypersurface. Semiclassical singularities of a given strength propagate across the hypersurface up to a threshold depending on the regularity of the potential and the singularities along certain backwards broken bicharacteristics.
