Static 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...
متن کاملIdentifying the Stern-Gerlach force of classical electron dynamics
Different classical theories are commonly applied in various branches of physics to describe the relativistic dynamics of electrons by coupled equations for the orbital motion and spin precession. Exemplarily, we benchmark the Frenkel model and the classical Foldy-Wouthuysen model with spin-dependent forces (Stern-Gerlach forces) to the quantum dynamics as predicted by the Dirac equation. Both ...
متن کاملGeneralized 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 کامل0 Semiclassical description of Stern - Gerlach experiments
The motion of neutral particles with magnetic moments in an inhomoge-neous magnetic field is described in a semi-classical framework. The concept of Coherent Internal States is used in the formulation of the semiclassical approximation from the full quantum mechanical expression. The classical trajectories are defined only for certain spin states, that satisfy the conditions for being Coherent ...
