The Aharonov - Bohm effect for an exciton
We study theoretically the exciton absorption on a ring shreded by a magnetic flux. For the case when the attraction between electron and hole is short-ranged we get an exact solution of the problem. We demonstrate that, despite the electrical neutrality of the exciton, both the spectral position of the exciton peak in the absorption, and the corresponding oscillator strength oscillate with mag...

متن کاملInduction Produces Aharonov - Bohm Effect
A charge e, moving with the velocity v through a time-constant space-varying magnetic potential field A, experiences a force of motional induction given by F v A = − ⋅ ∇ e c a f. Although the magnetic field is zero, B = 0; this force acts on the electrons passing on the two sides of a long sole-noid to produce the phase shift difference observed in the Aharonov-Bohm effect. PACS 03.65 – Quantum...
متن کامل. Non - stationary Aharonov - Bohm effect
Noise in an ac biased junction. Non-stationary Aharonov-Bohm effect. Abstract We study excess noise in a quantum conductor in the presence of constant voltage and alternating external field. Due to a two particle interference effect caused by Fermi correlations the noise is sensitive to the phase of the time dependent transmission amplitude. We compute spectral density and show that at T = 0 th...
متن کاملDispersionless forces and the Aharonov-Bohm effect
The independence of the Aharonov-Bohm phase shift on particle velocity is one of its defining properties. The classical counterpart to this dispersionless behavior is the absence of forces along the direction of motion of the particle. A reevaluation of the experimental demonstration that forces are absent in the AB physical system is given, including previously unpublished data. It is shown th...
