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. Distributions are nongaussian and agree well with random matrix theory calculations that account for a finite dephasing time, \(\tau_\phi\), once broadening...

Description
Summary:Full distributions of conductance through quantum dots with single-mode leads are reported for both broken and unbroken time-reversal symmetry. Distributions are nongaussian and agree well with random matrix theory calculations that account for a finite dephasing time, \(\tau_\phi\), once broadening due to finite temperature \(T\) is also included. Full distributions of the derivatives of conductance with respect to gate voltage \(P(dg/dV_g)\) are also investigated.
