Magnon delocalization in ferromagnetic chains with long-range correlated disorder
Rodrigo P. A. Lima, Marcelo L. Lyra, Elton M. Nascimento +1
We study one-magnon excitations in a random ferromagnetic Heisenberg chain with long-range correlations in the coupling constant distribution. By employing an exact diagonalization…

Quantum percolation in power-law diluted chains
Rodrigo P. A. Lima, Marcelo L. Lyra
We investigate the quantum percolation problem in a diluted chain with long-range hopping amplitudes. Each bond is activated with probability , where is the dis…
