Conductance Distribution of a Quantum Dot with Non-Ideal Single-Channel Leads
arXiv:cond-mat/9406036 · doi:10.1103/PhysRevB.50.11263
Abstract
We have computed the probability distribution of the conductance of a ballistic and chaotic cavity which is connected to two electron reservoirs by leads with a single propagating mode, for arbitrary values of the transmission probability Gamma of the mode, and for all three values of the symmetry index beta. The theory bridges the gap between previous work on ballistic leads (Gamma = 1) and on tunneling point contacts (Gamma << 1). We find that the beta-dependence of the distribution changes drastically in the crossover from the tunneling to the ballistic regime. This is relevant for experiments, which are usually in this crossover regime. ***Submitted to Physical Review B.***
