Coulomb "blockade" of Nuclear Spin Relaxation in Quantum Dots
Y. B. Lyanda-Geller, I. L. Aleiner, B. L. Altshuler
We study the mechanism of nuclear spin relaxation in quantum dots due to the electron exchange with 2D gas. We show that the nuclear spin relaxation rate is dramatically affected b…
Coherent electron transport in a Si quantum dot dimer
L. P. Rokhinson, L. J. Guo, S. Y. Chou +4
We show that the coherence of charge transfer through a weakly coupled double-dot dimer can be determined by analyzing the statistics of the conductance pattern, and does not requi…
Calculation of dephasing times in closed quantum dots
Eli Eisenberg, Karsten Held, Boris L. Altshuler
Dephasing of one-particle states in closed quantum dots is analyzed within the framework of random matrix theory and Master equation. Combination of this analysis with recent exper…
Comment on PRB 59, 9195 (1999) and 62, 14061 (2000) by D. S. Golubev and A. D. Zaikin, and on cond-mat/0110495 by D.S. Golubev, A.D. Zaikin, and Gerd Schön
I. L. Aleiner, B. L. Altshuler, M. G. Vavilov
The relation between "non-perturbative analysis" of low temperature dephasing and the perturbation theory is discussed. Contributions missed in each order of the perturbation theor…
Anderson Orthogonality Catastrophe in Disordered Systems
Yuval Gefen, Richard Berkovits, Igor V. Lerner +1
We study the Anderson orthogonality catastrophe (AOC) in finite conductors with diffusive disorder. The disorder averaged logarithm of , the overlap between the ground states be…
Single parameter scaling in 1-D Anderson localization. Exact analytical solution
Lev I. Deych, A. A. Lisyansky, B. L. Altshuler
The variance of the Lyapunov exponent is calculated exactly in the one-dimensional Anderson model with random site energies distributed according to the Cauchy distribution. We der…
