Classical trajectories in quantum transport at the band center of bipartite lattices with or without vacancies
Here we report on anomalies in quantum transport at the band center of a bipartite lattice with vacancies, namely: no weak localization effect shows up, and when leads have a single channel the transmission is either one or zero. We propose that both are a consequence of the chiral symmetry and the...

| 520 | 3 | |a Here we report on anomalies in quantum transport at the band center of a bipartite lattice with vacancies, namely: no weak localization effect shows up, and when leads have a single channel the transmission is either one or zero. We propose that both are a consequence of the chiral symmetry and the large number of states at the band center. The probability amplitude associated with the eigenstate that gives unit transmission resembles a classical trajectory both with or without vacancies. The large number of states allows one to build up trajectories that elude the blocking vacancies explaining the absence of weak localization. |l eng | |
