Turbulence Hierarchy and Multifractality in the Integer Quantum Hall Transition
Anderson L. R. Barbosa, Tiago H. V. de Lima, Ivan R. R. Gonzalez +3
We offer a new perspective to the problem of characterizing mesoscopic fluctuations in the inter-plateau region of the integer quantum Hall transition. We found that longitudinal a…
Multifractal Magnetoconductance Fluctuations in Mesoscopic Systems
N. L. Pessoa, A. L. R. Barbosa, G. L. Vasconcelos +1
We perform a multifractal detrended fluctuation analysis of the magnetoconductance data of two standard types of mesoscopic systems: a disordered nanowire and a ballistic chaotic b…
Scaling theory for anomalous semiclassical quantum transport
M I Sena-Junior, A M S Macêdo
Quantum transport through devices coupled to electron reservoirs can be described in terms of the full counting statistics (FCS) of charge transfer. Transport observables, such as…
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…
Quantum dot to disordered wire crossover: A complete solution in all length scales for systems with unitary symmetry
A. M. S. Macedo
We present an exact solution of a supersymmetric nonlinear sigma model describing the crossover between a quantum dot and a disordered quantum wire with unitary symmetry. The syste…
