Conductance Fluctuations and Spin Symmetries in Quantum Dots
D. M. Zumbuhl, J. B. Miller, D. Goldhaber-Gordon +4
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…
Photocurrent, Rectification, and Magnetic Field Symmetry of Induced Current Through Quantum Dots
L. DiCarlo, C. M. Marcus, J. S. Harris
We report mesoscopic dc current generation in an open chaotic quantum dot with ac excitation applied to one of the shape-defining gates. For excitation frequencies large compared t…
Spin orbit effects in a GaAs quantum dot in a parallel magnetic field
B. I. Halperin, Ady Stern, Y. Oreg +3
We analyze the effects of spin-orbit coupling on fluctuations of the conductance of a quantum dot fabricated in a GaAs heterostructure. We argue that spin-orbit effects may become…
Decoherence in Nearly-Isolated Quantum Dots
J. A. Folk, C. M. Marcus, J. S. Harris
Decoherence in nearly-isolated GaAs quantum dots is investigated using the change in average Coulomb blockade peak height upon breaking time-reversal symmetry. The normalized chang…
Spin Degeneracy and Conductance Fluctuations in Open Quantum Dots
J. A. Folk, S. R. Patel, K. M. Birnbaum +3
The dependence of mesoscopic conductance fluctuations on parallel magnetic field is used as a probe of spin degeneracy in open GaAs quantum dots. The variance of fluctuations at hi…
Low-Temperature Saturation of the Dephasing Time and Effects of Microwave Radiation on Open Quantum Dots
A. G. Huibers, J. A. Folk, S. R. Patel +3
The dephasing time of electrons in open semiconductor quantum dots, measured using ballistic weak localization, is found to saturate below ~ 100 mK, roughly twice the electron base…
