We apply the lattice instability analysis to homogeneously strained single crystal with a flat or defected surface to demonstrate that, in the process of emission of dislocation by an unstable surface, prior to the breaking of atomic bonds, a vibrational mode localizes, foretelling the location and the manner of the impending microscopic catastrophic event.
We discuss the possibility of realizing a microscopic Stern--Gerlach magnet for electrons using counter-propagating bichromatic laser light. Absorption of two photons with frequency 0) combined with stimulated emission of one photon with frequency 2w allows for the conservation of energy, momentum, and angular momentum, The possibility of constructing such a device appears to be an open question,
The Aharonov-Bohm effect was conclusively established by a series of our electron interference experiments, with the help of some advanced techniques, such as coherent field-emission electron beams and microlithography. Using this fundamental principle behind the interaction of an electron wave with electromagnetic fields, new observation techniques were developed to directly observe microscopi...
