Schramm-Loewner evolution (SLE_\kappa) is a one-parameter family of random fractal curves arising as scaling limits of interfaces in two-dimensional statistical mechanics models. For \kappa \in (4, 8), the SLE_\kappa curve is self-intersecting but not space-filling, forming complementary connected components known as bubbles. In this talk, I will discuss the relationship between the conformal removability of SLE traces and connectivity of the bubble adjacency graph, as well as a sharp phase transition as \kappa varies.
