Aharonov-Bohm Day at Stony Brook
Wednesday, February 28th, 2007
The Aharonov-Bohm effect, also called the Ehrenberg-Siday-Aharonov-Bohm effect, is both fascinating and fundamental. It delineates a fundamental difference between quantum and classical physics, through the way that fields and potentials act on matter. Moreover, it has found fundamental connections to the mathematics of line bundles in modern differential geometry. Since the first paper by Yakir Aharonov and David Bohm in 1959, it has been the subject of application, controversy, and debate for over forty years. Numerous experiments have exhaustively confirmed the predicted phase shift in interfering charged and magnetic particles; but no experiment to date has explicitly tested for the presence of classical forces.
This mini-symposium will bring together experimentalist Herman Batelaan from the University of Nebraska-Lincoln, and theorist Tim Boyer of the City University of New York, who will together propose an experiment to test Boyer's prediction that the Aharonov-Bohm effect is due to classical electromagnetic lag forces. We hope to have many of the participating physicists in related fields, to play the role of antagonists to Batelaan and Boyer. The event will begin with a tutorial talk on the fundamentals of the Aharonov-Bohm and Aharonov Casher effects, to bring the audience up to speed. Following the tutorial, and before the three follow up talks, there will be time for informal discussion between all participants and guests. Because of the tutorial talk, and the intrinsically simple and elegant nature of the physics behind Aharonov-Bohm, undergraduate students in physics and related fields are also welcome and encouraged to attend.
