Aharonov–Bohm, n. Physics.|əˈhærənɒv bəʊm|
[The names of Yakir Aharonov, 20th-cent. Israeli physicist, and David Bohm (1917–92), U.S.-born physicist.]
Used attrib. (esp. in Aharonov–Bohm effect) with reference to a phenomenon predicted by Aharonov and Bohm in 1959 (Physical Rev. CXV. 485), whereby electrons propagating around a region containing magnetic flux acquire a phase-shift of their wave function proportioned to the linked flux.
1961Ann. Physics XVI. 177 The conventional Schrödinger treatment of the Aharonov-Bohm effect of inaccessible magnetic fields postulates the use of single-valued wave functions, even in a multiply connected region. 1987Nature 22 Oct. 676/1 Even more surprising..is the appearance of Aharonov-Bohm oscillations in some non-superconducting solid-state devices. 1989A. Leggett in P. Davies New Physics ix. 283/2 A macroscopic version of a quantum-mechanical effect, known as the Aharonov–Bohm effect. |
