We consider the problem of a semiclassical description of quantum chaotic transport, when a tunnel barrier is present in one of the leads. Using a semiclassical approach formulated in terms of a matrix model, we obtain transport moments as power series in the reflection probability of the barrier, whose coefficients are rational functions of the number of open channels M. Our results are therefore valid in the quantum regime and not only when M ≫ 1. The expressions we arrive at are not… 

Quantum transport in chaotic cavities with tunnel barriers

We bring together the semiclassical approximation, matrix integrals and the theory of symmetric polynomials in order to solve a long standing problem in the field of quantum chaos: to compute

Semiclassical Calculation of Time Delay Statistics in Chaotic Quantum Scattering

We present a semiclassical calculation, based on classical action correlations, of all moments of the Wigner–Smith time delay matrix, Q , in the context of quantum scattering through systems with

Electronic transport in three-terminal chaotic systems with a tunnel barrier

We consider the problem of electronic quantum transport through ballistic mesoscopic systems with chaotic dynamics, connected to a three-terminal architecture in which one of the terminals has a

Integrable systems and crystals for edge labeled tableaux

We introduce the edge Schur functions E that are defined as a generating series over edge labeled tableaux. We formulate E as the partition function for a solvable lattice model, which we use to show



Statistics of quantum transport in weakly nonideal chaotic cavities.

Using symmetric function expansions and a generalized Selberg integral, a systematic perturbation theory in 1-Γ(i) valid for an arbitrary number of channels is developed and explicit formulas up to second order are obtained for the average and variance of the conductance and the average shot noise.

A semiclassical matrix model for quantum chaotic transport

We propose a matrix model which embodies the semiclassical approach to the problem of quantum transport in chaotic systems. Specifically, a matrix integral is presented whose perturbative expansion

Semiclassical theory of chaotic conductors.

The Landauer conductance through chaotic ballistic devices in the semiclassical limit is calculated, to all orders in the inverse number of scattering channels without and with a magnetic field, explaining why the energy-averaged conductance of individual chaotic cavities, with disorder or "clean," agrees with predictions of random-matrix theory.

Semiclassical theory of chaotic quantum transport.

A refined semiclassical approach to the Landauer conductance and Kubo conductivity of clean chaotic mesoscopic systems and shows that including off-diagonal contributions to double sums over classical paths gives a weak-localization correction in quantitative agreement with results from random matrix theory.

Nonlinear statistics of quantum transport in chaotic cavities

In the framework of the random matrix approach, we apply the theory of Selberg's integral to problems of quantum transport in chaotic cavities. All the moments of transmission eigenvalues are

Random matrix theory of quantum transport in chaotic cavities with nonideal leads

We determine the joint probability density function (JPDF) of reflection eigenvalues in three Dyson's ensembles of normal-conducting chaotic cavities coupled to the outside world through both

Ehrenfest-time dependence of weak localization in open quantum dots.

Numerical simulations of weak localization in the open quantum kicked rotator confirm the prediction that the weak localization correction to the conductance of a ballistic chaotic cavity is suppressed if the Ehrenfest time exceeds the dwell time in the cavity.

Semiclassical approach to chaotic quantum transport

We describe a semiclassical method to calculate universal transport properties of chaotic cavities. While the energy-averaged conductance turns out governed by pairs of entrance-to-exit trajectories,

Conductance distribution of a quantum dot with nonideal single-channel leads.

The theory bridges the gap between previous work on ballistic leads and tunneling point contacts and finds that the beta-dependence of the distribution changes drastically in the crossover from the tunneling to the ballistic regime.
