This sluggishness is often ascribed to the free energy landscape containing multiple minima (basins) separated by high barriers. Here we show, using theory and numerical simulation, that the landscape is much rougher than is classically assumed. Deep in the glass, it undergoes a \"roughness transition\" to fractal basins. This brings about isostaticity at jamming and marginality of glassy states near jamming.
