Yakir Aharonov Scientist

Yakir Aharonov (Hebrew: יקיר אהרונוב‎; born on August 28, 1932 in Haifa, Israel) is an Israeli physicist specializing in quantum physics. He is a Professor of Theoretical Physics and the James J. Farley Professor of Natural Philosophy at Chapman University in California. He is also a distinguished professor in the Perimeter Institute and a professor emeritus at Tel Aviv University in Israel. He is president of the IYAR, The Israeli Institute for Advanced Research.His research interests are nonlocal and topological effects in quantum mechanics, quantum field theories and interpretations of quantum mechanics. In 1959, he and David Bohm proposed the Aharonov–Bohm effect for which he co-received the 1998 Wolf Prize.In 1988 Aharonov et al. published their theory of weak measurement, which does not disturb the quantum state being observed. This work was motivated by Aharonov's long time quest to experimentally verify his theory that apparently random events in quantum mechanics are caused by events in the future (two-state vector formalism). Verifying a present effect of a future cause requires a measurement, which would ordinarily destroy coherence and ruin the experiment. He and his colleagues were able to make weak measurements and verify the present effect of the future cause.
