Popis: | In the so-called magnetic Aharonov-Bohm effect, a quantum interference pattern shift is produced when electrons move in a magnetic field-free region, thus in absence of forces. Analogous fringe shifts are observed in interference experiments even when electrons travel through a magnetic field and are thus affected by magnetic forces. Because of the vast dedicated literature covering this subject it could require a non trivial effort to attain a comprehensive overview. Therefore, attention has been addressed: i) to recall the theory, ii) to describe the basic aspects of the main experiments realized up today and, iii) to review the long-standing debate regarding the interpretation of the Aharonov-Bohm phase shift as a new quantum topological effect with no analogue in classical theory, or as an energy-related lag effect based on classical forces. |
