Conductance peaks in open quantum dots
J. G. G. S. Ramos, D. Bazeia, M. S. Hussein +1
We present a simple measure of the conductance fluctuations in open ballistic chaotic quantum dots, extending the number of maxima method originally proposed for the statistical an…
Presence of asymmetric noise in multi-terminal chaotic cavities
A. L. R. Barbosa, J. G. G. S. Ramos, D. Bazeia
This work deals with chaotic quantum dot connected to two and four leads. We use standard diagrammatic procedure to integrate on the unitary group, to study the main term in the se…
Spin Accumulation Encoded in Electronic Noise for Mesoscopic Billiards with Finite Tunneling Rates
J. G. G. S. Ramos, A. L. R. Barbosa, D. Bazeia +1
We study the effects of spin accumulation (inside reservoirs) on electronic transport with tunneling and reflections at the gates of a quantum dot. Within the stub model, the calcu…
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…
