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…
Nonlinear Transport in a Quantum Point Contact due to Soft Disorder Induced Coherent Mode Mixing
A. M. Zagoskin, R. I. Shekhter
We show that the coherent mixing of different transverse modes, due to forward scattering of carriers by soft impurity- or boundary potentials leads to a nonlinear, asymmetric curr…
