Spin transport in disordered long-range interacting spin chain
Spin transport in disordered long-range interacting spin chain
Using a numerically exact technique we study spin transport and the evolution of spin-density excitation profiles in a disordered spin-chain with long-range interactions, decaying as a power-law, $r^{-\alpha}$ with distance and $\alpha<2$. Our study confirms the prediction of recent theories that the system is delocalized in this parameters regime. Moreover …
