Anomalous Diffusion in Dipole- and Higher-Moment Conserving Systems
Johannes Feldmeier, Pablo Sala, Giuseppe de Tomasi +2
The presence of global conserved quantities in interacting systems generically leads to diffusive transport at late times. Here, we show that systems conserving the dipole moment o…
Distinguishing localization from chaos: challenges in finite-size systems
D. A. Abanin, J. H. Bardarson, G. De Tomasi +7
We re-examine attempts to study the many-body localization transition using measures that are physically natural on the ergodic/quantum chaotic regime of the phase diagram. Using s…
Density propagator for many-body localization: finite size effects, transient subdiffusion, and exponential decay
Soumya Bera, Giuseppe De Tomasi, Felix Weiner +1
We investigate charge relaxation in quantum-wires of spin-less disordered fermions (-model). Our observable is the time-dependent density propagator, ,…
Quantum Mutual Information as a Probe for Many-Body Localization
Giuseppe De Tomasi, Soumya Bera, Jens H. Bardarson +1
We demonstrate that the quantum mutual information (QMI) is a useful probe to study many-body localization (MBL). First, we focus on the detection of a metal--insulator transition…
