Scattering theory of superconductive tunneling in quantum junctions
V. S. Shumeiko, E. N. Bratus', G. Wendin
We present a consistent theory of superconductive tunneling in single-mode junctions within a scattering formulation of Bogoliubov-de Gennes quantum mechanics. Both dc Josephson ef…
Non-universal corrections to the level curvature distribution beyond random matrix theory
I. V. Yurkevich, V. E. Kravtsov
The level curvature distribution function is studied beyond the random matrix theory for the case of T-breaking perturbations over the orthogonal ensemble. The leading correction t…
On Asymptotic Properties of Large Random Matrices with Independent Entries
Alexei M. Khorunzhy, Boris A. Khoruzhenko, Leonid A. Pastur
We study the normalized trace $g_n(z)=n^{-1} \mbox{tr} \, (H-zI)^{-1}$ of the resolvent of real symmetric matrices assu…
Hidden Symmetry of the Differential Calculus on the Quantum Matrix Space
S. Sinel'shchikov, L. Vaksman
A standard bicovariant differential calculus on a quantum matrix space is considered. The principal result of this work is in observing that the $U_q\frak{s}(\fr…
Persistent current in a one-dimensional ring of fractionally charged "exclusons''
I. V. Krive, P. Sandström, R. I. Shekhter +1
The Aharonov-Bohm effect in a one-dimensional (1D) ring containing a gas of fractionally charged excitations is considered. It is shown that the low temperature behavior of the sys…
