Stern-Gerlach experiments : past , present , and future
We review how the results of the original Stern-Gerlach experiment (1922) have been interpreted and how proposed variations of it can be used to answer old and new questions about nature.
Stern‐Gerlach Forces and Spin Splitters
I comment on suggestions that Stern‐Gerlach forces be used to separate ensembles of antiprotons in opposite spin states as a way of providing beams or ensembles of polarised antiprotons.
STERN, BARUT, AND GERLACH TODAY
We review some original and some current questions about the Stern Gerlach eect in light of Asim Barut’s work.
A full quantum analysis of the Stern-Gerlach experiment using the evolution operator method: analyzing current issues in teaching quantum mechanics
In this short Corrigendum we correct a little mistake (mainly in the sign) in the derivation of the evolution of the wave function in the Stern–Gerlach experiment that appears in our published paper.
Sources and Targets of Polarized H and D Ions
The Stern–Gerlach experiment showed for the first time the quantization of angular momentum, more precisely the quantization of a new degree of freedom later called electron spin. The observation…
Quantum entanglement, spin-1/2 and the Stern–Gerlach experiment
Basic aspects of quantum entanglement are illustrated in connection with the two-component wavefunction description of spin-1/2 particles. In particular, the time evolution of entanglement in the…
(The Stern-Gerlach experiment and the electron spin: a quasi history example)
The aim of this work is to use the concept of quasi history to analyze the form of didactical presentation of the physics contents. We intend to stress the changes made to the knowledge, since the…

Is There An Abstract Wave Function
This paper gives a hypothesis about state and a formulation about quantum system. This formulation has no inside conflict, needn’t any abstract boundary and can connect state with reality. Its…
Stern-Gerlach experiment with arbitrary spin: Temporal evolution and entanglement
Abstract.Because it has disclosed basic quantum properties and concepts, the Stern-Gerlach experiment (SGE) has been fundamental for the development of quantum mechanics; for example, it was…
