Structure of a spin 1/2

TL;DR

This paper investigates non-Hermitian states related to Bell states, predicts a new spin-1/2 quantum state, and shows how decoherence leads to conventional spin descriptions, enhancing understanding of spin structure.

Contribution

It introduces a novel quantum state of spin 1/2 arising from non-Hermitian states and analyzes their properties and ensemble formation.

Findings

Prediction of a new spin-1/2 state with zero net angular momentum.

Demonstration that isolated spins are resonance states.

Ensemble averaging aligns with standard quantum spin models.

Abstract

The non-hermitian states that lead to separation of the four Bell states are examined. In the absence of interactions, a new quantum state of spin magnitude 1/(root(2) is predicted. Properties of these states show that an isolated spin is a resonance state with zero net angular momentum, consistent with a point particle, and each resonance corresponds to a degenerate but well defined structure. By averaging and de-coherence these structures are shown to form ensembles which are consistent with the usual quantum description of a spin.
