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…
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…
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…
