u approaches 1/2m, where m=1,2,3.... A tunneling experiment is proposed in which dramatic changes in the I-V characteristic should be observable as
u is varied. Explicit I-V characteristics calculated within the so-called Modified Random Phase Approximation, are provided for
u=1/3 ->
u=1/2. | Source: | arXiv, cond-mat/9711081 | Services: | Forum | Review | PDF | Favorites |
