Abstract | : |
In generic systems with local interactions transport is diffusive, though it can be supressed by the addition of disorder. Introducing long-range interactions, should intuitively, enhance transport by long-range hop. Using numerically exact techniques I will show that this is not the case for a number of generic one-dimensional systems. All studied systems, for sufficiently short-range interactions, show universal behaviour of asymptotically emergent locality and a unique composite transport comprised of diffusive and superdiffusive features. Introducing disorder, slows down the transport and makes it subdiffusive, similarly to the situation for local systems. |
