Excitation transfer in disordered spin chains with long-range exchange interactions
Excitation transfer in disordered spin chains with long-range exchange interactions
We examine spin excitation or polarization transfer via long-range interacting spin chains with diagonal and off-diagonal disorder. To this end, we determine the mean localization length of the single-excitation eigenstates of the chain for various strengths of the disorder. We then identify the energy eigenstates of the system with large …
