Flat-band quantum communication induced by disorder
G. M. A. Almeida, R. F. Dutra, A. M. C. Souza +2
We show that a qubit transfer protocol can be realized through a flat band hosted by a disordered spin-1/2 diamond chain. In the absence of disorder, the transmission becomes…
Delocalization in harmonic chains with long-range correlated random masses
F. A. B. F. de Moura, M. D. Coutinho-Filho, E. P. Raposo +1
We study the nature of collective excitations in harmonic chains with masses exhibiting long-range correlated disorder with power spectrum proportional to , where is the…
Delocalization and spin-wave dynamics in ferromagnetic chains with long-range correlated random exchange
F. A. B. F. de Moura, M. D. Coutinho-Filho, E. P. Raposo +1
We study the one-dimensional quantum Heisenberg ferromagnet with exchange couplings exhibiting long-range correlated disorder with power spectrum proportional to , where …
