1 Nov 1999 | | Journal: | Phys. Rev. Lett. 84, 3927 (2000) DOI: 10.1103/PhysRevLett.84.3927 | | Subject: | Disordered Systems and Neural Networks; Mesoscopic Systems and Quantum Hall Effect | cond-mat.dis-nn cond-mat.mes-hall | | Abstract: | The supersymmetry technique [A. V. Kolesnikov and K. B. Efetov, Phys. Rev. Lett. 83, 3689 (1999)] predicts a two-scale behavior of wavefunction decay in disordered wires in the crossover regime from preserved to broken time-reversal symmetry. We have tested this prediction by a transmission approach, relying on the Borland conjecture that relates the decay length of the transmittance to the decay length of the wavefunctions. Our numerical simulations show no indication of two-scale behavior. | | Source: | arXiv, cond-mat/9910517 | | Services: | Forum | Review | PDF | Favorites | |
