Aharonov-Bohm Oscillations in a One-Dimensional Wigner Crystal-Ring
I. V. Krive, R. I. Shekhter, S. M. Girvin +1
We calculate the magnetic moment (`persistent current') in a strongly correlated electron system --- a Wigner crystal --- in a one-dimensional ballistic ring. The flux and temperat…
Noise in a Quantum Point Contact due to a Fluctuating Impurity Configuration
J. P. Hessling, Yu. Galperin, M. Jonson +2
We propose a theoretical model for the low-frequency noise observed in a quantum point contact (QPC) electrostatically defined in the 2D electron gas at a GaAs-AlGaAs interface. In…
Influence of Long-Range Coulomb Forces and Dissipation on the Persistent Current of a Wigner Crystal-Ring
I. V. Krive, P. Sandström, R. I. Shekhter +1
The influence of long-range Coulomb forces on the persistent current of a pinned Wigner crystal-ring is considered. A simple method is proposed for how to take into account Coulomb…
Non-Equilibrium Magnetization in a Ballistic Quantum Dot
T. Swahn, E. N. Bogachek, Yu. M. Galperin +2
We show that Aharonov-Bohm (AB) oscillations in the magnetic moment of an integrable ballistic quantum dot can be destroyed by a time dependent magnetic flux. The effect is due to…
