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 …
