Interaction of the 4-rotational gauge field with orbital momentum, gravidiamagnetic effect, and orbit experiment "Gravity Probe B"

TL;DR

This paper explores a new Poincaré gauge theory of gravitation where the 4-rotational gauge field interacts directly with orbital angular momentum, predicting observable effects such as orbit precession and gyroscope torsion interaction.

Contribution

It introduces a novel gauge-theoretic framework where tetrads are functions of gauge fields, leading to new gravitational effects like gravidiamagnetic precession and gyroscope-torsion interaction.

Findings

Prediction of electronic orbit precession under external gravitational fields

Theoretical support for gyroscope interaction with torsion field

Potential detection of effects by Gravity Probe B experiment

Abstract

The direct interaction of the 4-rotational (Lorentzian) gauge field with the angular orbital momentum of an external field is considered. This interaction appears in a new Poincar\'{e} gauge theory of gravitation, in which tetrads are not true gauge fields, but represent some functions of the translational and 4-rotational gauge fields. The given interaction leads to a new effect: the existence of an electronic orbits precession under the action of an intensive external gravitational field (gravidiamagnetic effect), and also substantiates the existence of the direct interaction of the proper angular momentum of a gyroscope with the torsion field, which theoretically can be generated by the rotational angular momentum of the planet the Earth. The latter interaction can be detected by the experiment Gravity Probe B on the satellite orbit.
