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…
Spectral fluctuations effects on conductance peak height statistics in quantum dots
K. Held, E. Eisenberg, B. L. Altshuler
Within random matrix theory for quantum dots, both the dot's one-particle eigenlevels and the dot-lead couplings are statistically distributed. While the effect of the latter on th…
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…
The breakdown of the Nagaoka phase in the 2D t-J model
E. Eisenberg, R. Berkovits, D. A. Huse +1
In the limit of weak exchange, J, at low hole concentration, the ground state of the 2D t-J model is believed to be ferromagnetic. We study the leading instability of this Nagaoka…
Ground State Spin Structure of Strongly Interacting Disordered 1D Hubbard Model
E. Eisenberg, R. Berkovits
We study the influence of on-site disorder on the magnetic properties of the ground state of the infinite U 1D Hubbard model. We find that the ground state is not ferromagnetic. Th…
Disorder Induced Ferromagnetism in Restricted Geometries
E. Eisenberg, R. Berkovits
We study the influence of on-site disorder on the magnetic properties of the ground state of the infinite Hubbard model. We find that for one dimensional systems disorder has n…
