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…
Optical manipulation of bipolarons in a system with nonlinear electron-phonon coupling
K. Kovač, D. Golež, M. Mierzejewski +1
We investigate full quantum mechanical evolution of two electrons nonlinearly coupled to quantum phonons and simulate the dynamical response of the system subject to a short spatia…
Transition to the Haldane phase driven by electron-electron correlations
A. Jażdżewska, M. Mierzejewski, M. Środa +4
One of the most famous quantum systems with topological properties, the spin antiferromagnetic Heisenberg chain, is well-known to display exotic e…
Relaxation mechanisms in a disordered system with the Poisson level statistics
Janez Bonca, Marcin Mierzejewski
We discuss the interplay between many-body localization and spin-symmetry. To this end, we study the time evolution of several observables in the anisotropic t-J model. Like the Hu…
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…
Semiclassical bounds on dynamics of two-dimensional interacting disordered fermions
Łukasz Iwanek, Marcin Mierzejewski, Anatoli Polkovnikov +2
Using the truncated Wigner approximation (TWA) we study quench dynamics of two-dimensional lattice systems consisting of interacting spinless fermions with potential disorder. Firs…
