The Ehrenberg–Siday–Aharonov–Bohm effect in graphene rings

The Ehrenberg–Siday–Aharonov–Bohm effect in graphene rings Quantum interference in mesoscopic ring structures based on graphene can be influenced by external magnetic field. As was first predicted by Ehrenberg and Siday in 1949, a magnetic field piercing a ring creates vector-potential along the ring, which changes the phase of the electronic de Broglie waves. This effect has now been confirmed by experiments on graphene rings. Graphene is a novel material, which brought a Nobel prize to Novoselov and Geim, who discovered it. Novel, graphene-specific features discovered on graphene rings include so-called Klein tunneling and specular Andreev reflection.
