Conductance Fluctuations and Spin Symmetries in Quantum Dots
arXiv:cond-mat/0501622 · doi:10.1103/PhysRevB.72.081305
Abstract
Conductance fluctuations in GaAs quantum dots with spin-orbit and Zeeman coupling are investigated experimentally and compared to a random matrix theory formulation that defines a number of regimes of spin symmetry depending on experimental parameters. Accounting for orbital coupling of the in-plane magnetic field, which can break time-reversal symmetry, yields excellent overall agreement between experiment and theory.
