abstract
We propose an infrared cut-off for the holographic the dark-energy, which besides the square of the Hubble scale also contains the time derivative of the Hubble scale. This avoids the problem of causality which appears using the event horizon area as the cut-off, and solves the coincidence problem.

HDE models with future event horizon IR cutoff partially ease the Hubble tension while Hubble-scale cutoffs do not, consistent across six models and multiple BAO/SN/CMB combinations.
The paper derives new dark energy models from the postulate that the arbitrary oscillator mass in a free field's Hamiltonian is a real, gravitating mass contributing vacuum energy density μK^3.
