Eigenstate thermalization at the edge of the many-body spectrum
Arnav Pushkar, Pranay Patil, Soumya Bera +2
It is well-known that thermalization breaks down in presence of an extensive number of symmetries or conservation laws that are mutually compatible or commuting with each other. We…
Slow dynamics and strong finite-size effects in many-body localization with random and quasi-periodic potential
Felix Weiner, Ferdinand Evers, Soumya Bera
We investigate charge relaxation in disordered and quasi-periodic quantum-wires of spin-less fermions (-model) at different inhomogeneity strength in the localized and n…
Accessing eigenstate spin-glass order from reduced density matrices
Younes Javanmard, Soumya Bera, Markus Heyl
Many-body localized phases may not only be characterized by their ergodicity breaking, but can also host ordered phases such as the many-body localized spin-glass (MBL-SG). The MBL…
Sharp entanglement thresholds in the logarithmic negativity of disjoint blocks in the transverse-field Ising chain
Younes Javanmard, Daniele Trapin, Soumya Bera +2
Entanglement has developed into an essential concept for the characterization of phases and phase transitions in ground states of quantum many-body systems. In this work, we use th…
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…
