Searching for dark torsion signatures at LIGO in Nieh–Yan teleparallel chiral gravitational waves and Chern–Simons invariants
Published 2024-12-01“…In particular, nonhomogeneous and nonuniform chiral chemical potential generates GWs and dark torsion from primordial magnetic fields. It is shown that pulsar sources for GWs bathing the surface of the Earth on a contortion background of $$10^{-15}\,\textrm{s}^{-1}$$ 10 - 15 s - 1 possess amplitudes well within the parameters of LIGO capabilities of amplitudes on the order of $$10^{-22}$$ 10 - 22 . …”
