Evidence for valence-bond pairing in a one-dimensional two-orbital system
M. Mierzejewski, E. Dagotto, J. Herbrych
Valence bond (VB) states as the formation mechanism of Cooper pairs, eventually leading to high-temperature superconductivity, remain a controversial topic. Although various VB-lik…
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…
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 …
Spin diffusion in perturbed isotropic Heisenberg spin chain
S. Nandy, Z. Lenarčič, E. Ilievski +3
The isotropic Heisenberg chain represents a particular case of an integrable many-body system exhibiting superdiffusive spin transport at finite temperatures. Here, we show that th…
Ballistic transport in integrable quantum chains with degenerate spectra
M. Mierzejewski, J. Herbrych, P. Prelovsek
We study the ballistic transport in integrable lattice models, i.e., the spin XXZ and Hubbard chains, close to the noninteracting limit. The stiffnesses of spin and charge currents…
Many-body localization as a percolation phenomenon
P. Prelovšek, M. Mierzejewski, J. Krsnik +1
We examine the standard model of many-body localization (MBL), i.e., the disordered chain of interacting spinless fermions, by representing it as the network in the many-body (MB)…
