A Novel Aharonov-Bohm Effect: Macroscopic Quantum Phase Transition Induced by the Vector Potential
Dr. Raymond Chao has observed an asymmetric hysteresis loop, whose asymmetry is induced by vector potential arising from the ferromagnetic core of a lead-coated torus, in a tin ring that is topologically linked with this torus, upon transitions through the critical temperature and critical field of this tin ring.
Q&A and refreshments after the lecture.
