| Random matrix approach to `nonuniversal' conductance (1997) | |||||||||
Abstract | |||||||||
| Recent experiments on the conductance of high quality quantum wires have revealed an unexpected feature: the quantization step of the conductance is apparently system dependent. We provide the understanding of this behaviour using the appropriately extended random matrix approach. A single additional parameter governs the size of the conductance quantization steps. In effect the behaviour seems to remain `universal', generic for the conductance of a class of mesoscopic systems.. Comment: 4 pages in LaTex + 4 figures in .eps submitted to Phys. Rev. B | |||||||||
