The anisotropic Heisenberg model close to the Ising limit: triangular lattice vs. effective models
Martin Ulaga, Jure Kokalj, Takami Tohyama +1
Stimulated by recent experiments on materials representing the realization of the anisotropic Heisenberg spin- model on the triangular lattice, we explore further properties o…
Slow diffusion and Thouless localization criterion in modulated spin chains
P. Prelovšek, J. Herbrych, M. Mierzejewski
In recent years the ergodicity of disordered spin chains has been investigated via extensive numerical studies of the level statistics or the transport properties. However, a clear…
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…
Thermal conductivity and heat diffusion in the two-dimensional Hubbard model
Martin Ulaga, Jernej Mravlje, Peter Prelovšek +1
We study the electronic thermal conductivity and the thermal diffusion constant in the square lattice Hubbard model using the finite-temperature L…
From dissipationless to normal diffusion in easy-axis Heisenberg spin chain
P. Prelovšek, S. Nandy, Z. Lenarčič +2
The anomalous spin diffusion of the integrable easy-axis Heisenberg chain originates in the ballistic transport of symmetry sectors with nonzero magnetization. Ballistic transport…
Relaxation at different length-scales in models of many-body localization
J. Herbrych, M. Mierzejewski, P. Prelovšek
We study dynamical correlation functions in the random-field Heisenberg chain, which probes the relaxation times at different length scales. Firstly, we show that the relaxation ti…
