Excitons in quantum-ring structures in a magnetic field: Optical properties and persistent currents
A. O. Govorov, A. V. Kalameitsev, R. Warburton +2
We study theoretically the magnetic field effect on a neutral, but polarizable exciton confined in quantum-ring structures. For excitons with a nonzero dipole moment, a novel magne…
Magnetoexcitons in quantum-ring structures: a novel magnetic interference effect
S. E. Ulloa, A. O. Govorov, A. V. Kalameitsev +2
A novel magnetic interference effect is proposed for a neutral, but polarizable exciton in a quantum ring with a finite width. The magnetic interference effect originates from the…
Universal Features of Interacting Chaotic Quantum Dots. Application to Statistics of Coulomb Blockade Peak Spacings
Victor Belinicher, Eran Ginossar, Shimon Levit
We present a complete classification of the electron-electron interaction in chaotic quantum dots based on expansion in inverse powers of , the number of the electron states i…
Instanton picture of the spin tunneling in the Lipkin model
Victor I. Belinicher, Constanca Providencia, Joao da Providencia
A consistent theory of the ground state energy and its splitting due to the process of tunneling for the Lipkin model is presented. For the functional integral in terms of the spin…
Quantum wires and dots driven by intense surface acoustic waves and the quantum attenuation of sound in an electron plasma
A. O. Govorov, A. V. Kalameitsev, V. M. Kovalev
We develop a quantum theory of the nonlinear interaction between intense surface acoustic waves and electrons of a quantum well in the regime of moving quantum wires and dots. The…
