Comment on "Absence of electron dephasing at zero temperature"
Dmitri S. Golubev, Andrei D. Zaikin, Gerd Schön
The recent claim by Kirkpatrick and Belitz (cond-mat/0111398) that Ward identities could be used to prove the absence of electron dephasing at T=0 contains serious flaws. These aut…
Superconductor Quantum Dot Superconductor Junction in the Kondo Regime
Y. Avishai, A. Golub, A. D. Zaikin
Electron transport between two superconductors through an Anderson impurity in the Kondo regime is investigated within the slave boson mean field approximation. The current, shot n…
On Low-Temperature Dephasing by Electron-Electron Interaction
D. S. Golubev, A. D. Zaikin, Gerd Schön
The quantum coherence of electrons can be probed by studying weak localization corrections to the conductivity. Interaction effects lead to dephasing, with electron-electron intera…
Coulomb Effects and Electron Transport Through a Coherent Conductor
A. D. Zaikin, D. S. Golubev
We analyze electron transport through relatively short coherent conductors in the presence of Coulomb interaction. We evaluate the current-voltage characteristics of such conductor…
Comparison between Theory and Some Recent Experiments on Quantum Dephasing
Dmitrii S. Golubev, Andrei D. Zaikin
We report on a quantitative comparison between our theory of quantum dephasing at low temperatures and some recent experimental results [D. Natelson {\it et al.}, Phys. Rev. Lett.…
