We investigate canonical, phantom and quintom models, with the various fields being non-minimally coupled to gravity, in the framework of holographic dark energy. We classify them and we discuss their cosmological implications. In particular, we examine the present value of the dark energy equation-of-state parameter and the crossing through the phantom divide, and we extract the conditions for a future cosmological singularity. The combined scenarios are in agreement with observations and reveal interesting cosmological behaviors.

  1. Constraints on Barrow and Tsallis Holographic Dark Energy from DESI DR2 BAO data

    gr-qc 2025-06 conditional novelty 5.0 of 10

    Barrow and Tsallis holographic dark energy models fit DESI DR2 data but are disfavored by information criteria versus LambdaCDM and do not ease the Hubble tension.

  2. Topological dark energy from black-hole formations and mergers through the gravity-thermodynamics approach

    gr-qc 2024-12 reject novelty 5.0 of 10

    Black hole formation and merger, through topology changes of the cosmic apparent horizon, generate an effective dark energy whose equation of state is phantom-like or quintessence-like depending on the sign of the Gau...
