abstract

The coupling of space-time torsion to the Dirac equation leads to effects on the energy levels of atoms which can be tested by Hughes-Drever type experiments. Reanalysis of these experiments carried out for testing the anisotropy of mass and anomalous spin couplings can lead to the till now tightest constraint on the axial torsion by $K \leq 1.5 . 10^{-15} m^{-1}$.

  1. Tidal Forces in the Presence of Torsion and Nonmetricity

    gr-qc 2026-06 unverdicted novelty 6.0 of 10

    Tidal acceleration of autoparallels in metric-affine gravity separates into Newtonian gravity plus linear post-Riemannian corrections from torsion and nonmetricity that can be decomposed into irreducible Lorentz components.

  2. `Translation invariant' black hole: autoparallels and complete integrability

    gr-qc 2025-06 conditional novelty 6.0 of 10

    Autoparallel motion in a class of torsionful Schwarzschild spacetimes is completely integrable via four conserved quantities, and positive-energy autoparallels are repelled by the black hole.
