Generalized Stern-Gerlach effect for chiral molecules.
The Stern-Gerlach effect is well known as spin-dependent splitting of a beam of atoms with magnetic moments by a magnetic-field gradient. Here, we show that an induced gauge potential may lead to a similar effect for chiral molecules. In the presence of three inhomogeneous light fields, the center of mass of a three-level chiral molecule is subject to an optically induced gauge potential, and t...
متن کاملSpin and the Stern - Gerlach Experiment
The word “quantum” means a single share or portion. In quantum mechanics, this means that energy comes in discrete chunks, or quanta, rather than a continuous flow. But it also means that particles have other properties that are discrete in a way that’s deeply counterintuitive. Today I want to tell you about one such property, called spin, and the experiment that discovered it: the Stern-Gerlac...
متن کاملStern-Gerlach Experiment and Bohm Limit
Stern-Gerlach experiment is a paradigm of measurement theory in quantum mechanics. Notwithstanding several analysis given in literature, no clear understanding of the apparent collapse has been given so far. Indeed, one can imagine a Stern-Gerlach device where all environmental effects are removed and ask the question on how the measurement goes on. In this letter we will prove that a the Stern...
متن کاملQuantum-mechanical analysis of a longitudinal Stern-Gerlach effect.
We present the results of a rigorous quantum-mechanical calculation of the propagation of electrons through an inhomogeneous magnetic field with axial symmetry. A complete spin polarization of the beam is demonstrated assuming that a Landau eigenstate can be inserted into the field. This is in contrast with the semiclassical situation, where the spin splitting is blurred.
متن کاملStatic Stern-Gerlach effect in magnetic force microscopy
The Stern-Gerlach ~SG! effect, one of the cornerstones of a quantum mechanics, still attracts much attention. ~See, for example, Refs. @1–7#.! The SG apparatus clearly demonstrates the quantization of angular momentum and it can also demonstrate the mysterious puzzles of quantum measurement, macroscopic quantum superposition ~Schrödinger-cat! states, and decoherence. The SG effect was used to m...
