Diffusion in interacting two-dimensional systems under a uniform magnetic field
Åukasz Iwanek, Marcin Mierzejewski, Adam S. Sajna
The dynamics of interacting particles in orbital magnetic fields are notoriously difficult to study, as this physics is inherently connected to electronic correlations in two-dimen…
Spin subdiffusion in perturbed infinite-U Hubbard chain
Jakub RÄkas, Marcin Mierzejewski, Zala LenarÄiÄ +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…
