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…
Local integrals of motion in dipole-conserving models with Hilbert space fragmentation
Patrycja Łydżba, Peter Prelovšek, Marcin Mierzejewski
Hilbert space fragmentation is an ergodicity breaking phenomenon, in which Hamiltonian shatters into exponentially many dynamically disconnected sectors. In many fragmented systems…
Emergent dipole moment conservation and subdiffusion in tilted chains
S. Nandy, J. Herbrych, Z. Lenarčič +3
We study the transport dynamics of an interacting tilted (Stark) chain. We show that the crossover between diffusive and subdiffusive dynamics is governed by , where …
Finite-temperature properties of the easy-axis Heisenberg model on frustrated lattices
Martin Ulaga, Jure Kokalj, Alexander Wietek +2
Motivated by recent experiments on a compound {displaying Ising-like short-range correlations on the triangular lattice, we study the anisotropic easy-axis spin- Heisenberg mo…
Cavity-mediated thermal control of metal-to-insulator transition in 1T-TaS
Giacomo Jarc, Shahla Yasmin Mathengattil, Angela Montanaro +10
Placing quantum materials into optical cavities provides a unique platform for controlling quantum cooperative properties of matter, via both weak and strong light-matter coupling.…
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…
Reduced-basis approach to many-body localization
Peter Prelovšek, Osor S. Barišić, Marcin Mierzejewski
Within the standard model of many-body localization, i.e., the disordered chain of spinless fermions, we investigate how the interaction affects the many-body states in the basis o…
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…
Self-consistent approach to many-body localization and subdiffusion
P. Prelovšek, J. Herbrych
An analytical theory, based on the perturbative treatment of the disorder and extended into a self-consistent set of equations for the dynamical density correlations, is developed…
Universal dynamics of density correlations at the transition to many-body localized state
M. Mierzejewski, J. Herbrych, P. Prelovšek
Within one-dimensional disordered models of interacting fermions we perform a numerical study of several dynamical density correlations, which can serve as hallmarks of the transit…
Decay of density waves in coupled one-dimensional many-body-localized systems
Peter Prelovšek
The behavior of coupled disordered one-dimensional systems, as modelled by identical fermionic Hubbard chains with the on-site potential disorder and coupling emerging through the…

Osor S. Barišić, Jure Kokalj, Ivan Balog +1
We present a numerical study of the many-body localization (MBL) phenomenon in the high-temperature limit within an anisotropic Heisenberg model with random local fields. Taking th…

Transport quantities of the classical spin chain with the quenched disorder in the antiferromagnetic coupling are evaluated using the dynamical simulation at finite temperatu…

Peter Prelovšek, Jure Kokalj, Zala Lenarčič +1
We study the binding of a holon to a doublon in a half-filled Hubbard model as the mechanism of the zero-temperature metal-insulator transition. In a spin polarized system and a no…

Dawid Crivelli, Marcin Mierzejewski, Peter Prelovšek
We discuss the energy current and the energy fluctuations in an isolated quantum wire driven far from equilibrium. The system consists of interacting spinless fermions and is drive…
Eigenvalue statistics of reduced density matrix during driving and relaxation
M. Mierzejewski, T. Prosen, D. Crivelli +1
We study a subsystem of an isolated one-dimensional correlated metal when it is driven by a steady electric field or when it relaxes after driving. We obtain numerically exact redu…
