Distributions of the Conductance and its Parametric Derivatives in Quantum Dots

Full distributions of conductance through quantum dots with single-mode leads are reported for both broken and unbroken time-reversal symmetry. The distributions are non-Gaussian and agree well with random matrix theory calculations that account for a finite dephasing time, ${\tau }_{\varphi }$, once broadening due to a finite temperature $T$ is also included. Full distributions of the derivatives of conductance with respect to gate voltage $P\left({dg/dV}_g\right)$ are also investigated.
