Finding local integrals of motion in quantum lattice models in the thermodynamic limit
J. Pawlowski, J. Herbrych, M. Mierzejewski
Local integrals of motion (LIOMs) play a key role in understanding the long-time properties of closed macroscopic systems. They were found for selected integrable systems via compl…

Thouless approach in transport in integrable and perturbed easy-axis Heisenberg chains
J. Pawlowski, M. Mierzejewski, P. Prelovsek
We study transport in spin chains employing the Thouless approach based on the level sensitivity to the boundary conditions, . Although spin transport in the integrable easy-axi…

Long-living prethermalization in nearly integrable spin ladders
J. Pawlowski, M. Panfil, J. Herbrych +1
Relaxation rates in nearly integrable systems usually increase quadratically with the strength of the perturbation that breaks integrability. We show that the relaxation rates can…
