Finite-frequency noise, Fano factor, -noise and cross-correlations in double quantum dots
A. Crépieux, T. Q. Duong, M. Lavagna
A theoretical study on electrical current fluctuations in a double quantum dot connected to electronic reservoirs is presented, with the aim of deriving the finite-frequency noise,…
Level anticrossing effect in single-level or multilevel double quantum dots: Electrical conductance, zero-frequency charge susceptibility and Seebeck coefficient
M. Lavagna, V. Talbo, T. Q. Duong +1
We study electrical and thermoelectrical properties for a double quantum dot system. We consider the cases of both single-level and multilevel quantum dots whatever the way they ar…
Non-symmetrized quantum noise in a Kondo quantum dot
A. Crépieux, S. Sahoo, T. Q. Duong +2
The fluctuations of electrical current provide information on the dynamics of electrons in quantum devices. Understanding the nature of these fluctuations in a quantum dot is thus…
Nonsymmetrized noise in a quantum dot: Interpretation in terms of energy transfer and coherent superposition of scattering paths
R. Zamoum, M. Lavagna, A. Crépieux
We calculate the nonsymmetrized current noise in a quantum dot connected to two reservoirs by using the non-equilibrium Green function technique. We show that both the current auto…
One-channel conductor coupled to a quantum of resistance: exact ac conductance and finite-frequency noise
R. Zamoum, A. Crepieux, I. Safi
We consider a one-channel coherent conductor with a good transmission embedded into an ohmic environment whose impedance is equal to the quantum of resistance R_q=h/e^2 below the R…
Electron injection in a nanotube: noise correlations and entanglement
A. Crepieux, R. Guyon, P. Devillard +1
Transport through a metallic carbon nanotube is considered, where electrons are injected in the bulk by a scanning tunneling microscope tip. The charge current and noise are comput…
Anomalous Hall effect and weak localization corrections in a ferromagnet
A. Crépieux, J. Wunderlich, V. K. Dugaev +1
In this paper, we report results on the anomalous Hall effect. First, we summarize analytical calculations based on the Kubo formalism : explicit expressions for both skew-scatteri…
