No late-time role for adiabatic torsion: a no-go result for Hubble-cutoff holographic dark energy in Einstein–Cartan cosmology

Abstract In Friedmann cosmology with Einstein–Cartan torsion, the homogeneous torsion mode compatible with a separately conserved matter sector scales as $$\Phi \propto a^{-3}$$ Φ ∝ a - 3 and enters the Friedmann constraint as a stiff component of negative energy density, $$-3\Ph...
