It's all in GR: spinors, time, and gauge symmetry

TL;DR

This paper demonstrates deriving spinor fields and their dynamics from the geometric structures of General Relativity, linking spinors to vielbeins and gauge symmetry through scalar time fields.

Contribution

It introduces a novel geometric approach to incorporate spinor fields into General Relativity using vielbeins and gauge symmetry principles.

Findings

Spinor fields can be derived from vielbein geometry.

The spinor action is connected to a scalar time field.

A new geometric interpretation of spinors in GR.

Abstract

This paper shows how to obtain the spinor field and dynamics from the vielbein and geometry of General Relativity. The spinor field is physically realized as an orthogonal transformation of the vielbein, and the spinor action enters as the requirement that the unit time form be the gradient of a scalar time field.
