Strongly disordered Anderson insulator chains with generic two-body interaction
B. Krajewski, L. Vidmar, J. Bonca +1
The random-field spin-1/2 XXZ chains, and the corresponding Anderson insulators of spinless fermions with density-density interaction, have been intensively studied in the context…

Modelling sample-to-sample fluctuations of the gap ratio in finite disordered spin chains
Bartosz Krajewski, Marcin Mierzejewski, Janez Bonča
We study sample-to-sample fluctuations of the gap ratio in the energy spectra in finite disordered spin chains. The chains are described by the random-field Ising model and the Hei…
