One-magnon excitations in Heisenberg ferromagnetic chains with power-law decaying random interactions
We investigate the nature of one-magnon excitations in disordered quantum Heisenberg ferromagnetic chains with long-range interactions. The exchange coupling between a given pair of sites (i,j) is considered to be randomly distributed with asymptotic power-law decaying variance ?J?1/
