Anomalous quantum transport in low-dimensional lattice systems
Abstract:
Transport that deviates from standard diffusive behaviour is often called anomalous. Anomalous transport often appears in low-dimensional systems, but its microscopic origin remains unclear. In the first part of my talk, I will discuss anomalous sub-diffusive phases that appear in clean short and long-range fermionic lattice systems and their origin by connecting the conductance scaling with the exceptional point physics of the underlying non-Hermitian transfer matrix. I will then talk about how anomalous transport appears for long-range lattice models with and without external dephasing sources.
