This work is devoted to the thermodynamics description of a phantom scenario proposed previously by the authors. The presence of negative chemical potential is unavoidable if we allege for a well defined thermodynamics framework since the cosmological model passages from phantom stage at present time to a future de Sitter evolution. As noted earlier in other works, we find that the negativity of the chemical potential is necessary to save phantom dark energy from thermodynamics inconsistencies.

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

    gr-qc 2026-07 accept novelty 6.0

    The adiabatic Einstein–Cartan torsion mode cannot rescue Hubble-cutoff holographic dark energy: it is dynamically inert and bounded to Ω_Φ < 5×10⁻²⁴ by BBN.
