Generalized correlation functions for conductance fluctuations and the mesoscopic spin Hall effect
J. G. G. S. Ramos, A. L. R. Barbosa, D. Bazeia +2
We study the spin-Hall conductance fluctuations in ballistic mesoscopic systems. We obtain universal expressions for the spin and charge current fluctuations, cast in terms of curr…
Crossover of thermal to shot noise in chaotic cavities
A. L. R. Barbosa, J. G. G. S. Ramos, D. Bazeia
We study the crossover between thermal and shot-noise power in a chaotic quantum dot in the presence of non-ideal contacts at finite temperature. The result explicitly demonstrates…
Diagrammatic Analysis of the Unitary Group for Double Barrier Ballistic Cavities: Equivalence with Circuit Theory
Anderson L. R. Barbosa, Antonio M. S. Macedo
We derive a set of coupled non-linear algebraic equations for the asymptotics of the Poisson kernel distribution describing the statistical properties of a two-terminal double-barr…
