Spin subdiffusion in perturbed infinite-U Hubbard chain
Jakub Rękas, Marcin Mierzejewski, Zala Lenarčič +1
The -model represents the Hubbard model in the limit and is one of the basic models of strongly correlated electrons. On a one-dimensional chain, the model is int…
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…
Einstein relation for subdiffusive relaxation in Stark chains
Peter Prelovšek, Sourav Nandy, Marcin Mierzejewski
We investigate chains of interacting spinless fermions subject to a finite external field (also called Stark chains) and focus on the regime where the charge thermalization fol…
Multiple relaxation times in perturbed XXZ chain
M. Mierzejewski, J. Pawłowski, P. Prelovšek +1
We numerically study the relaxation of correlation functions in weakly perturbed integrable XXZ chain. The decay of the spin-current and the energy-current correlations at zero mag…
Transient and persistent particle subdiffusion in a disordered chain coupled to bosons
P. Prelovsek, J. Bonca, M. Mierzejewski
We consider the propagation of a single particle in a random chain, assisted by the coupling to dispersive bosons. Time evolution treated with rate equations for hopping between lo…
Density correlations and transport in models of many-body localization
P. Prelovšek, M. Mierzejewski, O. Barišić +1
We present a review of recent theoretical results concerning the many-body localization (MBL) phenomenon, with the emphasis on dynamical density correlations and transport quantiti…
