Extracting Hidden Symmetry from the Energy Spectrum
Emil A. Yuzbashyan, William Happer, Boris L. Altshuler +1
In this paper we revisit the problem of finding hidden symmetries in quantum mechanical systems. Our interest in this problem was renewed by nontrivial degeneracies of a simple spi…
On the "non-perturbative analysis" of zero-temperature dephasing: I. Dyson equation and self energy
I. L. Aleiner, B. L. Altshuler, M. G. Vavilov
We point out that the structure of the self-energy suggested in cond-mat/0208140 as a result of a ``non-perturbative analysis'' by ``purely mathematical means'' is incompatible wit…
Random matrix theory for closed quantum dots with weak spin-orbit coupling
K. Held, E. Eisenberg, B. L. Altshuler
To lowest order in the coupling strength, the spin-orbit coupling in quantum dots results in a spin-dependent Aharonov-Bohm flux. This flux decouples the spin-up and -down random m…
Ability to Count to Two. Opening Talk at the Third International Sakharov Conference on Physics
Boris L. Altshuler
Third International Sakharov Conference on Physics organized by the Theoretical Physics Department of the Lebedev Institute, Russian Academy of Sciences, covered wide scope of topi…
Calculation of the Observationally Small Cosmological Constant in the Model of Six-Dimensional Warped Brane-Bolt World
Boris L. Altshuler
In the 6-dimensional model of warped compactification based on the euclidean AdS Reissner-Nordstrom metric it is possible to escape artificial 4-brane's stress-energy tensor anistr…
Quantum in-plane magnetoresistance in 2D electron systems
Julia S. Meyer, Vladimir I. Fal'ko, B. L. Altshuler
We review various aspects of magnetoresistance in (quasi-)twodimensional systems subject to an in-plane magnetic field. Concentrating on single-particle effects, three mechanisms l…
