Mesoscopic fluctuations of nonlinear conductance of chaotic quantum dots
Mikhail L. Polianski, Markus Buttiker
TL;DR
This paper analytically studies mesoscopic fluctuations in the nonlinear conductance of chaotic quantum dots, considering magnetic flux effects, temperature, and interactions, and compares results with experimental data.
Contribution
It provides a comprehensive analytical framework for conductance fluctuations in chaotic quantum dots, including magnetic flux symmetry and dephasing effects, with experimental validation.
Findings
Conductance fluctuations are symmetric or antisymmetric under magnetic flux inversion.
Dephasing effects are significant in few-channel quantum dots.
Theoretical results align well with recent experimental observations.
Abstract
The nonlinear dc conductance of a two-terminal chaotic cavity is investigated. The fluctuations of the conductance (anti)symmetric with respect to magnetic flux inversion through multichannel cavities are found analytically for arbitrary temperature, magnetic field, and interaction strength. For few-channel dots the effect of dephasing is investigated numerically. A comparison with recent experimental data is provided.
