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 ( $t - V$ -model). Our observable is the time-dependent density propagator, $Π_{ε} (x, t)$ ,…

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…

Generalized Dyson model: nature of zero mode and its implication in dynamics

Giuseppe De Tomasi, Sthitadhi Roy, Soumya Bera

We study the role of the anomalous $E = 0$ state in dynamical properties of non-interacting fermionic chains with chiral symmetry and correlated bond disorder in one dimension. These…
