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,…
Dynamical charge susceptibility in nonequilibrium double quantum dots
A. Crépieux, M. Lavagna
Double quantum dots are one of the promising two-state quantum systems for realizing qubits. In the quest of successfully manipulating and reading information in qubit systems, it…
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…
Charge susceptibility and conductances of a double quantum dot
V. Talbo, M. Lavagna, T. Q. Duong +1
We calculate the charge susceptibility and the linear and differential conductances of a double quantum dot coupled to two metallic reservoirs both at equilibrium and when the syst…
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…
Emission Noise in an Interacting Quantum Dot: Role of Inelastic Scattering and Asymmetric Coupling to the Reservoirs
A. Crépieux, S. Sahoo, T. Q. Duong +2
A theory is developed for the emission noise at frequency in a quantum dot in the presence of Coulomb interactions and asymmetric couplings to the reservoirs. We give an analyt…
Out-of-equilibrium Kondo Effect in a Quantum Dot: Interplay of Magnetic Field and Spin Accumulation
Shaon Sahoo, Adeline Crépieux, Mireille Lavagna
We present a theoretical study of low temperature nonequilibrium transport through an interacting quantum dot in the presence of Zeeman magnetic field and current injection into on…
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…
Finite-frequency noise in a non-interacting quantum dot
Redouane Zamoum, Mireille Lavagna, Adeline Crépieux
We calculate the non-symmetrized finite-frequency NS-FF noise for a single-level quantum dot connected to reservoirs in the spinless non-interacting case. The calculations are perf…
Reply to the comment on "Theoretical analysis of the transmission phase shift of a quantum dot in the presence of Kondo correlations"
M. Lavagna, P. Vitushinsky, A. Jerez
In their comment, Aharony, Entin-Wohlman, Oreg and von Delft claimed that the expression we obtained for the phase of the S-matrix does not give back the correct result notably in…
