In this talk, we focus on the corrections to Bekenstein-Hawking entropy by associating it with the entanglement between degrees of freedom inside and outside the horizon. Using numerical techniques, we show that the corrections proportional to fractional power of area result when the field is in a superposition of ground and excited states. We explain this result by identifying that the degrees of freedom contributing to such corrections are different from those contributing to Bekenstein-Hawking entropy.

  1. Power-Law and Logarithmic Entropy-Corrected Ricci Dark Energy in a Non-Flat FRW Universe with Viscous Interaction

    gr-qc 2025-08 reject novelty 4.0 of 10

    Analytic expressions are derived, with algebra errors, for two entropy-corrected Ricci dark energy models and their formal correspondence to Chaplygin gas, Yang-Mills, and NLED scalar field models.
