Oscillations in the magnetoconductance autocorrelation function for ballistic microstructures
We present a comparison between experiment and theory for the magnetoconductance autocorrelation function C(DB) for transport through a stadium-shaped ballistic microstructure. The correlation function displays damped oscillations which can be traced to the quantum interference between bundles of short trajectories. We present two different semiclassical calculations applicable for large and sm...
متن کاملAsymptotic Expansion for the Magnetoconductance Autocorrelation Function
We complement a recent calculation (P.B. Gossiaux and the present authors, Ann. Phys. (N.Y.) in press) of the autocorrelation function of the conductance versus magnetic field strength for ballistic electron transport through microstructures with the shape of a classically chaotic billiard coupled to ideal leads. The function depends on the total number M of channels and the parameter t which m...
متن کاملCrossover of magnetoconductance autocorrelation for a ballistic chaotic quantum dot
The autocorrelation function Cφ,ε(∆φ, ∆ε) = 〈δg(φ, ε) δg(φ+∆φ, ε+∆ε)〉 (φ and ε are rescaled magnetic flux and energy) for the magnetoconductance of a ballistic chaotic quantum dot is calculated in the framework of the supersymmetric non-linear σ-model. The Hamiltonian of the quantum dot is modelled by a Gaussian random matrix. The particular form of the symmetry breaking matrix is found to be r...
